I basically put points into Speed and Intelligence in roughly equal proportions, but only the one into CON in char creation. I am getting additional SPD, INT and CON from items, though. Here are my current stats, just before level 12 (that point will probably go into Speed, since I have quite a good deal of INT).

Level 11
HP = 657
AP (Start/Max/Turn) = 11 / 16 / 10


STR = 5
DEX = 6 (+1 Gear)
INT = 15 (+4 Gear, +1 Codex)
CON = 9 (+3 Gear)
SPD = 13 (+3 Gear)
PER = 5 (+1 Gear, -1 Codex)

Movement = 4.36 meters/AP
((Base 1.00 + Gear + 1.34 + Speed 1.30) * 20% Swift Footed)
