[alpinar]

i salut you all again

So im at the gremlin boss and after a few tryes at him hi rips my units apart totally meanwhile i only get him to like 70%(im lvl 45 mage on normal)...i have 10 red dragons,9 green dragons,and 7 black dragons plus 81 paladins and like 87 shamans and this combo doesnt work really here...i have read on the forums abit and found ashort thread about the boss but didnt help alot..i was thinking horsemens,canon dwarfs (for the towers)paladins ,red dragons and royal griffins ..and guess what red dragons lows the moral for the griffins and they do like 35% lesser dmg plus lower resis..will be thankfull for andy advice or tips,regards Alpina
