my paladin is lvl 17 now on impossible.
finaly i have found a tactic that works and picked skills and monsters that works well with it.
important skills
order magic 3 : to rez lvl 4 mobs
tactic2 : to be able to attack first round
mobs
griffins : best unit. unlimited retaliations togheter with psycial resist buffs
royal snakes: with frog wife and snake boots they do very good damage are hard to kill and have long movement
orc shamans : perfect to use totems to make enemy waste attacks and have an usefull range attack sometimes
archmagis : have one good skill : shield, perfectt boost up griffins
cannoners : range unit. can be replaced by any ranged units. i prefer evil beholders under ground elfs over ground and cannoners upgrading stuff.
i have also found jade belt witch increase damage for spiders with 50% and thorn crown wich do the same for thorns. mayby i will change range unit for royal thorns or fire spiders later on if i can find them in masses.
