Does the double-bladed scimitar’s special attack let you use your ability modifier for the damage of the attack?

I am using the double-bladed scimitar with the Revenant Blade feat from Wayfinder’s Guide to Eberron.

The double-bladed scimitar’s special feature (p. 74):

Special. When you take the attack action and make a two-handed attack with a double-bladed scimitar, you can use a bonus action to make a melee attack with the blade at the opposite end of the weapon. This attack uses the same ability modifier as the primary attack. The weapon’s damage die for this attack is a d4, and it deals slashing damage.

The part of the Revenant Blade feat (also on p. 74) that mentions the damage:

On your turn, when you use a bonus action to make a melee attack with the blade at the opposite end of the weapon, the weapon’s damage die for this attack increases to 2d4, instead of 1d4.

Let’s say I have 16 Dex, so a +3 to my dex mod. If I take the Attack action with the weapon, and use my bonus action for the weapon’s special function, do I add my Dex modifier to the damage of the special attack or not? Will it be 2d4+3, or just 2d4?

Does the Dragonfire Strike feat change the type of damage?

The Feat Dragonfire Strike has the following wording:

When you gain extra damage from a sneak attack, sudden strike, or skirmish, you can choose for the extra damage to be fire damage.

This makes it clear that the attack gains fire descriptor and it’s resulting immunities. What is unclear is what it does in relation to Sneak attack immunities, like that of Undead or Constructs.

I have two thoughts on this:

  1. This doesn’t change it from being a sneak attack, therefore creature immune to sneak attack are immune to Dragonfire Strike’s fire damage.

  2. This changes the attack from a sneak attack to a fire based attack thus bypassing Sneak Attack Immunity, but now susceptible to Fire Immunity instead.

Which is correct?

Ability Damage, spells, and the possession spell

Let’s say that a wizard casts Possession on a bugbear. Now, this bugbear has spent some time in questionable places and has contracted both Filth Fever and Mindfire, the first being a disease causing Dex and Con damage, the latter being a disease causing Int damage.

The wizard is still possession the bugbear when the diseases have their next ability damage ‘tick’. Who gets the ability damage?

The second paragraph of possession reads the following (Emphasis mine)

If you are successful, your life force occupies the host body. The host’s soul is imprisoned with you, but can still use its own senses (though it can’t assert any influence or use even purely mental abilities). You can communicate telepathically with the host as if you shared a common language, but only with your consent. You keep your Intelligence, Wisdom, Charisma, level, class, base attack bonus, base save bonuses, alignment, and mental abilities. The body retains its Strength, Dexterity, Constitution, hit points, natural abilities, and automatic abilities. A body with extra limbs doesn’t allow you to make more attacks (or more advantageous two-weapon attacks) than normal. You can’t activate the body’s extraordinary or supernatural abilities, nor can you cast any of its spells or spell-like abilities.

Because of this I assume that only the body would get the Dex and Con damage from Filth Fever, though I can’t find any rulings on this. But, what about the Int damage from Mindfire. Who gets the Int damage? The wizard, the bugbear or maybe even both? I find this a difficult question because there are two minds in the same body, unlike similar possession spells like Magic Jar which removes the original soul from the body.

On a related note (and if this should be a seperate question, I apologize), how would spells like feeblemind work when targeting a body inhabited by more than one mind?

If a Hexblade is using a sentient weapon, can they stack the weapons charisma stat with their own for attack and damage rolls?

So I’ve been working on a Half-Elf Hexblade for a bit now and decided he should have a moonblade, which is a sentient elven longsword. Sentient weapons can’t be pact weapons, but you can still choose to use charisma with them using hex warrior. Does the weapons own charisma stat then stack with yours for attack and damage rolls?

What would be the game balance implications for using the Gygax method for applying falling damage?

According to the rules, at the end of a fall, a creature takes 1d6 bludgeoning damage for every 10 feet it fell, to a maximum of 20d6. However, way back in Dragon Magazine #69, D&D co-creator Gary Gygax explained that the original intention was to apply 1d6 damage per ten feet fallen, cumulative. So, a creature would take the following damage according to the distance fallen:

  • 10 ft: 1d6
  • 20 ft: 3d6
  • 30 ft: 6d6
  • 40 ft: 10d6
  • 50 ft: 15d6
  • 60 ft+: 20d6 (max)

My question is, if this method of applying falling damage is used in 5e, what if any are the game balance implications? Would it make certain low-level spells overly powerful, for instance?

Does immunity to ability damage also mean immunity to ability drain?

In the SRD section on Special Abilities, ability damage and ability drain are both grouped under Ability Score Loss, and states that one is temporary while the other is permanent.

Are drain and damage considered the same thing? Does immunity to one mean both? Are there any examples of immunity to each or both that would show they are not the same thing?

If a Lizardfolk druid is in Wild Shape, and uses his Hungry Jaws trait, does he use the damage from the beast’s bite or the lizardfolk’s bite?

Lizardfolk have a feature that gives them natural weapons in the form of their jaws. This bite deals 1d6+Str damage.

Hungry Jaws. In battle, you can throw yourself into a vicious feeding frenzy. As a bonus action, you can make a special attack with your bite. If the attack hits, it deals its normal damage, and you gain temporary hit points (minimum of 1) equal to your Constitution modifier, and you can’t use this trait again until you finish a short or long rest. (VGM 113)

Assuming you transform into a beast shape with the ability to perform a bite, the Hungry Jaws trait should be available to you, as racial features transfer over when you transform if the new form is capable of them.

Given this circumstance, would you use the Lizardfolk’s racial bite, or the bite attack belonging to the new form?

Is there any way to adjust the damage type of the Eldritch Blast cantrip so that it does fire damage?

I’m looking to build a Roy Mustang (from FMA) style character, whose primary method attack is a fiery explosion. While there are many Fire-based spells and cantrips I can use, I’m focused on the interaction of the Kiss of Mephistopheles eldritch invocation (see Unearthed Arcana: Warlock & Wizard) and the eldritch blast cantrip. For this character, it would make more sense for him to launch a flame, rather than a beam of force, that explodes into a fireball.

Is there a RAW way to adjust the damage type of eldritch blast to fire? I would be happy with a partial damage split, as long as there is fire damage being dealt.

Conditions:

  • He has to be Warlock 5, but multi-classing is allowed

  • We are allowed to use the official material, plus UA material (after running it by the GM)

  • Magic items will work, but they will need to be somewhat easy to get ahold of.

Note: The GM would likely be fine with allowing me to change the damage type, but I’d prefer using existing content that allows this instead. There have been cases of “You changed a rule for them, so you should change a rule for me” and I want to avoid this.

When does the attacker choose the damage type dealt by a weapon with multiple damage options?

Take a longsword, for example. Does the attacker choose piercing or slashing before they make the attack roll, after the attack roll is made but before the damage roll, before they make the damage roll, or even as the last part of the attack, after all the numbers are said and done?
