30-40 -
greater harts and deer - sacrifice moongate ilshenar
just be sure not to attack the healers, and not the red ones either, as these are as powerful as titans
40-70 -
skeletons - yew graveyard or yew crypts - yew moongate
the graveyard is better if your healing means are limited, but the spawn isn't good. you can stand outside the fence anyway to shoot.
otherwise the crypts are better, as about 6 spawn there all the time.
if you stand just at the place where the stairs are, only one can hit you, and with dull copper armour you should only take a few points of damage.
70-90 -
earth elementals - sacrifice ilshenar, shame lvl1 or a bit from honor moongate ilshenar.
in the sacrifice spot, in the ratman cave there's three spawns of two earthys each, the left ones you can easily drag out one at a time.
if that place happens to be cramped, or camped, you could try a little more open spot. first go upwards from honor, then after the cave entrance down left, through the desert and further there you'll find three earthys to fight in a very large area.
there's also two banks near at the gargoyle city, and near the uppermost bank there's a healer(you have to go to the 2nd floor) to get rezzed. just be quick at the desert, as the efreets and sand vortex' can kill you quite fast.
80-90-120 -
rotting corpses - humility moongate ilshenar
where they spawn there's usually a lot of other undead, so it's good to lure the other ones out(can be tricky, but they don't go back in several hours)
at the right location shown you can teleport where they won't get to you, it can be a little tricky though as they have to be pretty near the ledge to not walk up to you.
you don't have to fight rc's if they happen to kill you, earthys can take you to 120, but the gains on them is best at the level mentioned.
except rc's anyway there's these(note: add more) which are good to train on, and only have a melee attack:
arctic ogre lord
ogre lord
orc brute
terathan avenger
ophidian knigt-errant/avenger
frost troll
skeletal/bone knight
snow elemental
cyclops
terathan warrior
stone harpy
