[Jack Simth]

Alneyan: yeah, but that effect takes class level 3, ECL 4 (for Stisnera, due to the Tiefling base), which costs 6000 exp; assuming you have hit 3000 exp (for level 2, ECL 3) that's everything Stisnera has encountered, all over again, beefed up a CR so the EXP gain doesn't drop.

Meanwhile, in just another 2000 exp, Aphrinsi will gain +2 AC, +2d8+2 HP, an extra trick, evasion, +1 str, +1 dex, increased saves, increased attack bonus, a size class increase (+8 str, + 4 con (another +8 HP (+2 for each Hit Die)), -2 dex, +2 natural armor, -1 AC, -1 to-hit, increased damage die size) leaving her with
Str 22, Dex 14, Con 19, Int 2, Wis 12, Cha 6
AC 15, Bite +7 melee (1d8+8) (or is that 1d8+9?)
(13 + 2d8+10) hp.

Further, Jacob will pick up some nifties - another 1d8+1 hp, 2 level 2 spell slots (one from wisdom bonus, one from advancement), +1 to Fort, Ref, and Will saves, +1 attack, Trackless step, and I believe an additional feat, selected from anything Jacob's qualified for.
