Rotom (3.5e Monster)

Combat
 (Su): A gust of eerie wind is summoned and sent out, covering two 5' squares per hit die (16 for the sample Rotom). It must start adjacent to Rotom, and the squares must be connected as a single area. All in the area take Cold damage equal to 3d6 + the Rotom's hit dice, double if they have the [Psionic] subtype. A successful Fortitude save (DC 16, Charisma-based) halves this damage. Additionally, all of Rotom's ability scores gain a +1 enhancement bonus for one minute. Multiple uses of the ability will increase the bonus by +1 each time, to a maximum of +6.

Ominous Wind may not be used two turns in a row.

 (Su): Rotom can possess electric objects at will, similar to a Ghost's Malevolence ability.

 (Ex): Rotom naturally sheds a flickering blue-white light out to 30 feet.

 (Ex): Rotom is naturally electric. By spending an action charging up, the next electricity effect used by Rotom (spell-like ability, spell, touch attack, whatever) has its save DC (if any) improved and damage increased. It must be used within 3 rounds, or the charge is lost, crackling brightly and briefly expanding the [[#Light|Light] effect to 100 feet for 1 round.
 * Standard action: +2 to the save DC, add 3d6 + Intelligence modifier to damage.
 * Full Round action: +4 to the save DC, double damage and add Intelligence modifier.

 (Sp): At will: shocking grasp, mirror image, shout, sonic snap; 1/5 rounds: lightning bolt, confusion, electric daze (Electricity effect: Reflex save or dazed 2 rounds, counts as a level 4 spell). Caster level equals hit dice, and the Save DCs are 10 + Spell Level + Rotom’s Charisma modifier.


 * The sample Rotom has a caster level of 5 and save DC of 12 + spell level.
