And you can make a successful Cleric/Thief unless that multiclass is barred for some reason for halflings.
It's not documented in the game but maybe the fact that Dwarves can't have maximum 18 Charisma and Gnomes and Halflings can't have maximum 18 Wisdom is some sort of a counterbalance mechanic due to how awesome their racial powers are. Any dwarf with 19 CON has some really serious saving throw boni, and a Gnomish Fighter/Illusionist with 18 CON is also a fun, safe build.
