ok here's the deal
make a list of the most annoying enemy stack u have to kill for a NO loss RUN
(and hopefully get a good tip too waste them
1. shamans( especially high stacks of shamans who can't be magic shackled
my tip for this enemy is too use mass magic shackles, it has a mass effect which keeps them doing only normal attack and not those pesky axes and totems which can deal a shitload of damage :O
2. black dragons
another big annoyce they are almost impossible to kill especially with a mage
my tip is trap(trap does work on black dragons
3. archidemons
oh boy they are pesky little bastards, they got alot of hp and do good damage
my tip be sure to be first and then place a trap
4. GIANTS (not very strong units but their special makes it horrible
tip is get alot of soaring or flying units. so their special is useless
5. high stacks of cyclopses
they take lots of damage before they die(they have alot of high physcial resistance and spells don't do much damage either)
i ussualy use a summoned unit to keep them busy while i aim with my archers on them)
6. brontors
make a summoned unit in front of them so they run to it
then hammer them with rest of the units
