Wizard Relic/Legendary idea that extends from UR idea and combines some previous ideas into something that seems reasonable to me.
Lenses of Focused Glare
+2 spell damage
Sacrifice an additional spell at same level. Upon successful spell check, 2x spell bonus (1/room)
Does not affect base spell damage -- only the bonus spell damage.
Used for wizard transmute. Relic has (1/room) and sacrifice any level spell, Legendary has (1/room) no spell sacrifice.
Relic:
Amulet of Coveted Power
+7 spell damage
Sacrifice any additional spell for 2x spell bonus (1/room)
Prismatic Ray
Legendary:
X's Arcane Amulet
+10 spell damage
2x spell bonus (1/room)
Keen Prismatic Ray
2x spell bonus
only doubles the spell modifier bonus and does not double the base damage of the spell. As an intentional action, use of this must be decided prior to spell cast.
Prismatic Ray:
Amulet has symbols around the edge for different damage types. Amulet can be slide as a Ray (ranged) spell attack against an enemy's true AC. It is considered a spell and receives the spell bonus modifier. Damage deals 1pt of damage + spell bonus damage as elemental damage dictated by the wheel.
This ray attack can crit on natural 20, follows normal crit rules (enemy must not be crit immune), and deals 2x full damage on a successful crit (includes the 2x spell bonus if active).
Keen Prismatic Ray increases crit range to 19-20.
I'm still wondering about tuning, but this is close-ish to what I expect the power level to be.
As an aside, I would like to see a design change for ray spells to be against the enemy's true AC and crit naturally on 20's.
