Also ... honestly, where else would you give your stats? O_o
CON for more health. DEX for more initiative.
WIS for saves. CHR to be a better face (Also, useful if utilizing racial spells)
Overall, there's plenty of options for sinking your stat points if you can ignore your main stat because you're able to set it to a value anyway. Which is something that can be abused with INT and DEX too with the Headband of Intellect and Gloves of Dexterity to get 19 INT and 18 DEX respectively (In Act 1 no less...). At least the CON item is Act 3 so you need to invest points into that stat for most of the game (While having 23 CON isn't as impactful as having a stat that affects attacks boosted)
