Well I've seen these changes on other Diablo 2 mods let's go.. about the mercenaries Mercenary of Act 1 Rogue Ice Type change the current skill Cold Arrow to Freezing Arrow.. Fire Type to Explosive Arrow (here you can equip some bows I know ... but in the case of the ice type there are no bows for that ) Mercenary Act 3 Iron Wolves add 1 Necromancer's Curse depending on what type follows... Fire Type Curse Amplify Damage, Ice Type curse Decrepify, Lightning Type curse Lower Resist. Mercenary act 5 Barbaros switch abilities to Berserk and Find Item. well I think that would be all for now these small changes would make the game play more interesting and all mercenaries more attractive ... currently 99.9 % of players only use the mercenary from act 2 ....
They cant use Any amazon Skills, it crushes game. U can check it yourself modding "hirelings" in data folder. Skills IDs are easy to fined in "skills". I offer you to check my suggetion for All mercs id u want, act1 included.
