Here’s a metamagic I’ve been kicking around for a bit.
When you cast a spell, you can spend a number of sorcery points equal to the spell’s level to have that spell repeat itself on one target affected by the spell at the start of the target’s next turn. (1 sorcery point if the spell is a cantrip). The target is allowed all saved and checks to avoid the spell as the spell allows.
Let’s keep the 7th level DnD spells rolling with a Wizard spell!
Casting Time 1 action
Range: 150 feet
Components: V, S
With a deafening plop a ball of acid explods in range coating everything in 30 feet in acid. All envviroments are covered dealing 12d6 acid damage to the ground,wallss,andd unattended objects. Creatures may attempt a Dexterity saving throw for half damage and to not be covered. If a creature is covered in acid, it will take additional damage at the start of each of it turns. Each turns after being covered, it takes damage equal to half the damage it took from the spell last turn. Each time it takes damage it may attempt another Dexterity saving throw to end the effect after taking damage. this effect continues until the amount of damage equals zero. In addition, an affected creature may scrap the acid of as an action to end the effect.
Let’s cross polinate the monk and the fighter in DnD 5e.
You have trained in the ways of flow, but you have also trained in the ways of force. Gain the following:
- Increase you Dexterity by 1, to a maximum of 20.
- Choose three maneuvers from the Battle Master Fighter list. You can use these by spending a ki point. The DC of any saves is equal to your KI save DC, and your superiority die is equal to your martial arts die value.
Let’s leave the warlock for a second and move on to the fighter. It’s nitch, but this is something that the battle master might want.
You are a master of combat who is fueled by death. Gain the following:
- Increase your Dexterity or Strength by 1, to a maximum of 20.
- Add 1 to your superiority dice.
- When you kill an enemy, regain one superiority dice instantly. There is no limit to the number of superiority dice you can gain this way, up to your maximum number.
Let’s make your find familiar better for the Warlock!
Prerequisite: 12th level, pact of the chain
When you choose this invocation, your master gifts you a better minion. Your choice of a familiar becomes an Incubus/succubus, a red dragon wyrmling, barbed devil, or a night hag.
Liking Starfinder, so let’s bring some ideas to DnD 5e! Here’s one for the pet class, the Warlock.
Prerequisite: 5th level
When you attack an enemy that you’re familiar is engaged with and your familiar has not attacked this round, you gain advantage on that attack while you’re familiar gains disadvantage.
If it works for Starfinder, it might work for DnD!
Your training from where you came from has prepared you as an adventurer. Choose one skill you gain proficiency from your background. Reduce the DCs for any use of this skill by 5. This includes opposed rolls.
