Ok that was just the motivation I needed to get the final cave done :P
Knockback units and knockback spells = win
I used:
Goblins, Tauren, Zombies, Mermaids, Centairs, and Witches.
Spells were: Immunity (whee :) ), Healing, Aoe stun, aoe freeze, meteor, and pheonix for giggles :P
Get the whole army up, wait till immunity is charged up, hit the castle, drop immunity, and try to use freeze + stun+ pheonix and co to keep that barely visible goblin back.
Done :)
(hero used is the green guy, he has the most mana from what I can tell (3500)
Basically you need 2 "tank units" (and titans are too expensive imo :P )
These guys stand in front and take the blows, their most important stats are: HP, HP, HP, HP, AOE attack, HP. You don't care how much damage they do, they just gotta take it.
Then your back row should consist of as many ranged you can field. The "best" for me are: Witches, Succubi, and the cannons. They all knock opponents around/multi hit/stun.
That leaves 1 slot for "fun stuff" which I usually take a healing crystal along to keep the front line happy.
Your front line is the most important, if it falls you die, keep them happy with spells ;)
When the opponents castle passes about 66% he spawns a "revenge wave" this is when you see if your defense stands or not... in other words: this is when all your units should be ready, and spells charged ;)
Nice idea + execution
I'd agree with the last one being easy after getting the max power drop :) I don't know if these are fix drops or random.
If its random, the last level would be rough :P
This way is much better: Updated "better strategy". This works perfectly fine on all levels. Premise: You buy shops and upgrades always after the waves (except on Day0, of course). Slots: Restaurant, Market, Furniture, Electronic, Jewelry, Boutique, Pet, Toy. Strategy: Day0:Pet&news(Pet), Day1:Bout, Day2:skip, Day3:skip, Day4:Pet2, Day5:skip, Day6:Bout2, Day7:Pet3, Day8:Toy, Day9:Bout3&Bus, Day10:Jewel&news(Jewel)&music(Bout), Day11:skip, Day12:Elec&music(Elec)&news(Furn), Day13:Furn, Day14:skip, Day15:Market, Day16:music(Market)&Jewel2, Day17:Elec2, Day18:Rest, Day19:Furn2, Day20:Jewel3, Day21:skip, Day22:Market2, Day23:Furn3, Day24:Elec3, Day25:skip, Day26:Market3, Day27:Rest2&Rest3, Day28-Day30:anything. Also, if on the last day of a level, you can upgrade the toyshop in the middle of the wave if you want. Keep it alive - copy
