I gave him him one at the same time I gave everyone else theirs:
Cal's mind-lock with the Kobold causes him to psionically steal one of the wyrmpriest's powers; He now has an additional encounter utility power called Incite Faith, usable as a minor action close burst 10, wherein his allies in the area gain 5 THP and may shift 1 square.
I felt that power would help boost your character's ability to protect his party, complementing the Blades of Astral Fire and The Light Within powers he's got. It's like giving everyone in the party an extra 5 hp, or temporary DR 5. Everyone's power right now is supposed to be roughly equal to a feat. Most people's powers are balanced against the Skill Power feat, which grants a utility power in exchange for a feat; Amnon's is equal to taking a Channel Divinity feat, which is fairly similar, and Gerand's just lets him use his Int for melee basic attacks, which he only really uses on Opportunity Attacks, so it, too, is fairly situational. Golkonda's ability is equivalent to the Arcane Familiar feat, which grants a couple minor benefits but is largely useful as a roleplaying device. This also gives me a chance to grant certain feats that might be interesting to players, but which they would normally skip since other feats are more useful or attractive.
Over time, everyone's bonus powers will improve, or you'll gain new abilities to complement them. For instance, Cal might gain a power that hurts or hinders an enemy, draining their resolve to bolster an ally and restore hp or grant a saving throw or something. Or if he tends to choose summon powers, he might gain an ability to extend the summon or sustain it without using extra actions. Or, I might continue the fluff of psionically leeching powers from enemies, granting a special ability from a monster that's normally unavailable to PCs.
Those are just examples; if you want, we can work together to custom-tailor your powers around your character. That goes for all of you.
I just want to provide something to help ease the anticipation of gaining new levels, since the pace of PbP is incredibly slow.
