The best combo we have found so far is........
Of course one cu sidhe (mainly for a damage absorber, due to its healing abilities, coupled with greater heals)
and here comes the part thats gonna cause the debate.....
A bake kitsune (as close to gm as possible, for magery, wrestling, and its special fury attack)
A Rune Beetle ( at least 120 poisoning, and a high wrestling/ for its ability to poison pretty consistently, high magery helps but is for only the ocassion self heal as they run outa mana rather quickly especially when doing peerless.)
Or............
You can go for the normal Greater Dragon (not that good for damage absorbtion with mid and low hp, and if low on wrestling skill (below 110) then your in for a very long kill)
The Bake/Rune beetle combo does as much damage as a Greater Dragon with the addition of poisoning and fury attacks (lowers
certain resists). Not recommended without the use of a cu sidhe as a damage absorber, due to the low hp on both the beetle and the bake.
Hope this helps, and yes, i have tried this combo many, many times with great success and dealt just as much damage as the guys using a greater.
