Kennel and Canine Handler
Hows about this
New Building:kennel
New Unit : Canine Handler
Upgrade progression (per kennel):
1 1 Handler and 1 dog
2 1 Handler 2 dogs (or large dog)
3 2 Handlers 4 dogs (or Wolf)
4 3 Handlers 4 Wolves (note past this point requires Elixer Cart)
5 3 Handlers 6 Wolves
6 4 Handlers 3 Dire Wolves
7 4 Handlers 6 Dire Wolves (note past this requires Dark Elixer cart)
8 4 Handlers 8 Dire Wolves
9 Dire Wolves can now jump walls
10 when the dire wolves land they cause 4d6 damage to units in the area
Limits
1 Kennels can NOT be inside walls
2 you have to have camp space for the handlers AND the dogs to use (L8+ would be the same cost as a low level giant)
3 the elixer cart (similar to the XBow one) CAN be looted
Attack
Land units only choice of multi or single targets (the Handler would function like a Barbarian the dogs would cause a low level but fast amount of damage plus the unit being attacked would not be able to fight anything else). The L10 jump damage would be spread to all units in range (so max total of 24 points)
Gem spending would be on the Kennels and of course Elixer Purchases
