Do you include the constitution modifier to your starting HP if it’s negative?

When I was creating my Bard with a standard array, I considered making constitution my lowest.

I know that starting HP = the highest number of your class’ hit dice + CON mod (so 8 + CON for a Bard)

But I’m wondering if that formula still applies if the modifier is negative. My friend says it doesn’t, and I’ve tried looking it up, but all I get is if it affects your HP leveling up, not your staring HP

How do I calculate my skill modifier?

I’m trying to fill out the skills section on my first character, but when I look at the character sheets in the Starter Set as examples of how to make a character, the skills that are circled have higher modifiers than their Dexterity or Strength or whatever should make them.

I’ve filled out all skills but those. What do I add to the ability modifier to get those numbers?

  • My abilities are Strength 13, Dexterity 14, Constitution 11, Intelligence 15, Wisdom 8, and Charisma 8.

  • Proficiencies are Arcana, Athletics, History, Investigation and Stealth.

  • My saving throws are Strength and Dexterity.

I just started D&D and have the Player’s Handbook, DM’s Guide, Monster Manual, and the Starter Set.

Attack modifier question for Paladin-Warlock multiclass. DnD 5e

I’m creating a fun villainous figure for my campaign. The choice has fallen on Paladin-Warlock hybrid. The general idea is to take 2 levels in Paladin for Divine Smite and then pound 4-5 levels into Hexblade Warlock. Blade-summoning for the flavour, good at all distances, quite mobile, and pretty tanky due to allowed armour-class.

The question is: Since warlock can use his CHA for attack rolls, will it combine with his STR or DEX modifier depending on the weapon or I’ll have to roll CHA instead of those stats?

What would the attack modifier be for an unarmed strike while wildshaped?

I know from a well voted for answer in Is a Wild Shape attack considered an unarmed strike? that it is possible for a druid to make an unarmed strike while wildshaped, just instead of the beast’s normal damage you would deal 1+STR (or otherwise for a monk or druid with Tavern Brawler), but what would the attack modifier be? A character is proficient in their unarmed strikes, so would they use proficiency bonus + strength modifier? Or would it just be straight strength modifier because they have no proficiency bonus, as their game statistics were replaced by the beast’s?

Can you add your the same modifier to damage rolls multiple times if they come from different instances?

A friend of mine is wanting to do a specific build and as far as I am aware you can not apply a modifier multiple times in this way. Can someone confirm if this is a RAW legal tactic?

Scenario: lv 6 tiefling celestial warlock, assuming 16 charisma

Cast shillelagh to make staff 1d8+cha [source: pact of the tome]

Then cast searing smite for 1d6+cha [source: teifling and celestial warlock’s radiant soul feature to add charisma mod]

Then green-flame blade attack for another 1d8+cha [celestial warlock’s radiant soul feature to add charisma mod]

A single hit would be 2d8+1d6+9

Do all these instances of charisma modifier stack like this?
