[Sir_Dr_D]

1) Recruit an independant mage who has nature magic
2) Get the mage to build some snake rings
3) Equip the snake rings on some theugs, and perhaps robes of missile protection.
4) Place each of these theugs amongst a group of 3 hydras.
5) Script -> body ethereal , body ethereal, body ethereal
6) Tell the Hydras to hold and attack
7) If needed back up the hydras with archers, and arch theugs casting lightning or other evocations. ( melee troops are pointless.)


End result: Devastation. A small group of hydras can take down entire armies.
