Just to make things easier so you're in line with the new cleric, you both gain 1000exp and are now lvl 2. Ghira gains 2 max hp, Talarin gains 3, both characters go to full health. Talarin, base attack is +1, will save goes to +3 base, spells per day go to 6 0-level and 4 1-level, spells known goes to 5 0-level, +5 skill points. Ghira, base attack to +1, base will save to +3, spells per day to 4 0-level and 2 1-level, +6 skill points.
Let me know what you want your skills to go to, I need to know Talarin's two new spells, and any changes to Ghira's starting spell list.
