Silicon Mummy

For effects targeting creatures by type, a silicon mummy counts as both a construct and as undead (whichever type allows an ability to affect them for abilities that affect only one type, and whichever is worse for abilities that affect both types).

A silicon mummy can absorb solar energy in the form of Solar Reserve Points (SRP), which they can spend in place of Resolve Points. For every 8 hours a silicon mummy spends exposed to the light of a star, the mummy gains 1 SRP, to a maximum number of SRPs equal to one-third their CR. For every week a silicon mummy absorbs no stellar energy, they lose 1 SRP. However, the mummy can intentionally enter a state of hibernation to lose only 1 point per 20 years, and although the mummy is aware of their surroundings and can fully animate as a move action, they are staggered for 1d4 hours afterward.

As a swift action, a silicon mummy can expend 1 SRP to enhance either their next melee attack, ranged attack, or spell before the end of their turn. An enhanced attack gains a +2 circumstance bonus to its attack roll and deals an additional 3d6 damage if it hits. An enhanced spell increases the spell’s saving throw DC by 2.

A silicon mummy’s protective exterior and nonfunctional organs limit critical damage; the mummy has a 25% chance (50% for CR 15+) to ignore the extra damage dealt by a critical hit and gains a +4 bonus to saves against critical hit effects.
