The Challenge in Dwarven Land

[Ryastar]

Easiest strategy (basically garunteed no-loss):

Dryads + level 1-3 non-mind immune troops. With this build, you can use dryads + phantom to keep ALL enemies asleep ALL THE TIME. This leaves you free to kill them off, one stack at a time.

Other general hints (for minimal losses):
-Don't use level 5 units, trust me, you will regret it when you face 2x your number of them
-another good strategy is a few ranged stacks, and the rest slow melee types. Kill of the opponent's ranged asap with spells/rage/your own ranged troops (onslaught makes this easier) and then slowly whittle away at the opponent's troops as they slowly approach you. However, this does mean that the opponent will be able to cast spells at you.
-all slowing abilities are essential, even if not using strategy from above. These include: (spells) slow(duh!), blind, pheonix (distraction!), demon portal (also distraction, though with time delay), hypnosis (only after you've weakened a stack), trap (careful placement is needed), necro call (if you manage to kill an enemy stack quickly). (rage) rock wall, ice thorns, ice ball (again, distraction), glot's armor (if desperate), any applicable troop + time back. (creature abilities) dryads' lullaby and summon thorns, shaman's totems, etc
