I want to make a video game based off of Dungeons and Dragons. How much am I legally permitted to use? [closed]

I want to make a video game based off of Dungeons and Dragons. It’ll be a top-down RPG with similar battle and class mechanics. But I’ve been planning out more, and seeing how much I’m copying. How much am I legally permitted to use? I am awayer of the SRD, but don’t understand it fully. Is it like a book of what I’m allowed to use?

How much damage is dealt/taken when that damage also reduces a creature to 0 hit points?

The particular case where this question came up was when a Hobgoblin Warlord attacked my ally, who had 7 hit points remaining. The attack’s damage was rolled for a total of 13, meaning they would fall unconscious. However, I am a Redemption Paladin which means I can Rebuke the Violent:

[…] Immediately after an attacker within 30 feet of you deals damage with an attack against a creature other than you, you can use your reaction to force the attacker to make a Wisdom saving throw. On a failed save, the attacker takes radiant damage equal to the damage it just dealt. […]

The question that arose was how to calculate "the damage it just dealt". Did the Hobgoblin Warlord deal 7 or 13 damage to my ally?


The only thing I found that somewhat answered this was the section on "Instant Death" which includes the following (emphasis mine):

[…] For example, a cleric with a maximum of 12 hit points currently has 6 hit points. If she takes 18 damage from an attack, she is reduced to 0 hit points, but 12 damage remains. Because the remaining damage equals her hit point maximum, the cleric dies.

This seems to state that the Cleric still takes 18 damage, even if her points drop to 0, but then it also states that 12 damage "remains". It’s not what I would call definitive and it doesn’t explicitly state that that is how damage works so I’m wondering if there’s anything that makes this even clearer.

How much XP does a monster created by Animate Objects add to an encounter?

I am making a boss fight. The boss can cast animate objects, a spell that can animate statues.

The spell gives information for, eg., 1 Large Construct:

Large – HP: 50, AC: 10, Attack: +6 to hit, 2d10 + 2 damage, Str: 14, Dex: 10

How much XP should I award for this Large construct?

I’m estimating CR1 (200XP) each.

How much loot (in GP) Should I be giving my players?

I’m very new to DMing. So I wan’t to get to a good start with the loot I give my players. We usually play in 2 hour sessions at college. This usually ends up being 1 days worth of in-game time. In this time I usually try to drop 2 Minor loot rewards, 1 Greater loot reward, and 0.5 Major loot reward (as I spread that over two 2-hour sessions).

How much loot (in GP) should I be giving my players each session to give them enough to pay for food and living, as well as purchase the occasional weapon or service?

I don’t want to drown them in money, devaluing the feeling of opening a chest of wealth, but I also don’t want to disappoint them by giving so little. Rather, just enough to keep them alive and going as well as ambitious to continue exploring dungeons and searching camp-sites. As I usually give rewards that are more sentimental or functional at the ends of quests (like Magic Items, Medals, Faction Invitations, and Benefits in the locations of the benefactor).

Because my players are changing in level and if similar DMs with different players refer to this question, could I please have an answer formatted to fit each level?

How much holy water is needed to cast Protection from Evil and Good?

In the PHB on page 270 we can read in the desription of Protection from Evil and Good that:

Components: V,S,M(holy water or powdered silver and iron, which the spell consumes)

Since the material components are consumed, they cannot be replaced with a spellcasting focus, as per the PHB (p.203)

If a spell states that a material component is consumed by the spell, the caster must provide this component for each casting of the spell.

This is reinforced by sage advice:

A spellcasting focus can be used in place of a material component only if that component has no cost noted in the spell’s description and if that component isn’t consumed.

The description does not list a cost in gp though. Which brings about the question above. While holy water is created in discrete 25gp “units”, powdered silver and iron are not, so we cannot just assume that you need 1 unit of holy water (ie. 25gp worth).

So, is a sprinkle of holy water enough? (Allowing the caster to use 1 unit for multiple castings.)

If one would use silver and iron, how much would they need? 25gp worth? Just “some”?
