So a thought occurred to me...which races can abuse equipment to get the highest possible stats? Some thoughts...
Elf Swashbuckler (Dex 19) with Hawksight (scimitar that gives +1 dex), Shuruppak's Plate (+1 dex), Malla's Soul Stone (+1 dex), Tome, Lum and Deck of Many Things = 25 dexterity.
Half Orc (Str19 Con19)
Tomes (+1 Str and +1 Con)
Hell (+2 Str and +2 Con)
Lum (+1 Str and +1 Con)
Deck of Many Things (+1 Str)
Axe of the Unyielding (+1 Con)
Malla's Soul Stone (+1 Con)
Alternatively, replace Axe of the Unyielding with the Harmonium Halberd for +1 strength. Giving 25 strength and 24 constitution. Note, that if he also has Shuruppak's Plate and has Hawksight in the offhand, and starts with 18dex, he will have Dexterity 22 as well.
I can't find any way to get both strength and constitution up to 25.
Any race (Wis18)
Deck of Many Things (+1)
Axe of Hrothgar if cleric/thief (+1) / Silver Ion Stone (+1)
Any race with at lest 16 Charisma or just with the ring of human influence
Helm of Glory (+1)
Blade of Roses (+2)
Nymph Cloak (+2)
Axe of Hrothgar (+1)
Charisma: 25 (Yes, even for a dwarf)
Anyone know any way to get that half-orc up to 25 strength? Also, how high can you Int?
