thanks for the detailed analysis jacquin. Now it makes more sense to me. All along my aim was to refrain from max lvl hard spells because of their cooling time, hence the array of lv1 spells in my shortcuts, because I believed that killing green mobs non-stop would gain exp faster than fighting yellow mobs, over time.

I've purchased the upgraded version of the spells, and currently using the combo by Jerath @ FiestaFan Wiki.

Ice(max)->Missle[01]->Bolt[max]->Missle[01]->Fire[01]->Missle[01]->Burst[max]->Missle[01]->Fire[01]->Missle[01]



Currently a lv27 now, executing the above combo I am able to kill a Marlone Clan Soldier, but I need to withstand at least 2 hits from him. THEN I will need to shroom, resulting in long waiting time. Should I go back to my dear grave robbers? I think grinding originally meant to attack mobs few levels lower then us to give optimum EXP over time.

The best thing you can do is find a party in MT-Goblin camp. For leveling.

The order of attack that i use when soloing

Ice(max), MM(max), Fire(max), Lightning(Max), MM(1), Magic Burst

Ice slows enemy giving more time, max MM because it has a 2.8 sec (5) cooldown, Magic burst after MM1 because the mob usually hasn't closed in yet, magic burst because it is a faster cast then two mm1's.
I don't know if this is the most effective, but I am killing Wild Imps, Flying Staffs, (and if I get a critical in) zombies before they can close the gap. (I am currently lvl 33)
