@spaceysnorlaxCan warlocks learn lower level spells as mystic arcana (eg circle of death as 7th or even dominate person as 6th)? As written, Mystic Arcanum doesn't allow spells of lower levels, but a DM could certainly allow it.

@ktkenshinxPolymorph says I cant take actions that use hands. Grapple action requires a free hand. Can Polymorphed PC use grapple? I would allow it if the beast form had an appendage or a bite that could potentially restrain someone.

@apollyonhelfirewould a hidden rogue add sneak attack damage to eldritch blast if they had it say from magic initiate feat or multiclass sneak attack specifies a ranged weapon, but I'd allow it in my campaign. on the powerful side, especially at high levels

@TheCriticalFailYou earlier stated whirlwind/volley is a single attack. Lightning arrow activates on all targets for huge aoe dmg? help? Lightning arrow affects a piece of ammunition, so it wouldn't work against all the targets of Volley.
