Other than that, don't neglect your thrown weapons in favor of spells. Good targets for this are screamers, swamp slimes, wizard eyes (maybe), rusters, vexirks, pain rats (maybe) oitus.ДЄlso I tend to literally punch out rockpiles and sometimes stone golems with shield spells up, but that only works for the tougher champions and I still have to retreat. Note that that means you should keep every dagger you find as IIRC they are the best melee weapon that increases ninja skills.(Somebody correct me if there is something better). In fact, on levels 3 and 6 I try to toss the dropped junk at monsters whenever possible, especially if they are out of melee range.ДЄlso for some of the easier monsters that you can tank, I like to equip daggers and melee them. I only toss it as I move, but if monsters are near I'll hold it until I can toss it at them. For grinding ninja skills, on some levels with creatures that drop junk I like to keep tossing about a club or falchon and let my lowest ranking ninja or weakest champion work on ninja skills.Work on something you use less often like fireshield (FUL BRO NETA), light (OH IR RA), or lightning bolt (OH KATH RA). I woudln't bother grinding magic torch except in the beginning after you first reincarnate, since it uses the same skill as fireball.

If somebody reaches full mana, I'd either cast ZO BRO ROS if I had an empty flask, or I'd work on one of the spells I use more rarely like casting fireshield or more rarely lightning bolt or poison cloud. The exception being when getting ready for a big fig like at the end of level 4 with 'This is my prisoner, let him suffer', or before facing the pain rat regeneration room, especially the first time.

My normal way to grind spells isn't really grinding, but having a policy of never letting my champions walk around with full mana.

Then again I rarely cast fireshield, pretty much only on level 8 (stray fireballs shooting around) and level 13 (with the black flames and demons).

I should note that it is usually easier to cast MON VI than PAL FUL BRO NETA in terms of success. Honestly, I never bothered to grind once I could cast any spell at PAL level.
