So I know that the Goblin has racial modifiers of STR-2, DEX+4, CHA-2. The Overesized Goblin template uses STR+2, DEX+2, CHA-2, and the Mutant Goblin template also replaces the mods with STR+4 and INT-2.
Is there a precedence for applying both templates for a PC that would generally be allowed (subject to DM approval, of course)?
