I have 4 wins in this game right now and fought 15 out of 20 different bosses:
| Boss | Army and ability | Strategy |
| Elven King | a lot of Elfs with increased range | Close the distance early so the Elfs can't shoot you. Trade off slow units before the fight. |
| The Nest | Giant Snails and plants | Plants poison you so make sure not to let the fight drag out. Keep a ranged unit alive to shoot the plants from afar after finishing off the snails. |
| Artemis | a lot of beasts with increased hp | - |
| Gigantomachy | several giants and cyclops and titans, forgot the ability | - |
| Dragon Master | several dragons, forgot the ability | - |
| Dracula | a big unit with several vampires | - |
| Necromancer Siege | Undead army with Plague | if you bring Undead army Plague won't matter |
| Hades | ??? | |
| Suleiman | Genies and Golems | Genies have magic damage and Golems are immune to magic. Never figured out how to abuse it. |
| Abandoned Mine | ??? | |
| Scorpion King | a big unit with a lot of insects and bonus damage | The most dangerous units are the ones with highest numbers because of bonus damage. Reduce their numbers first. |
| Gremlin Factory | Gremlins and Mechanical units | Ballista and Catapult don't retaliate so attack them quickly |
| Ctulhu | a very big unit with some ranged friends. Ctulhu deactivates skip turn skills and deals more damage to higher hp units (Maddening) | If you have units with skip turn skills, trade them off before the fight. Also try to trade very high hp units for lower hp units. |
| Beelzebub | two very big units and some demon garbage, forgot the ability | - |
| Ragnarok | three very big units and a lot of giants. Casts Armageddon that makes all units burn for 3 hp. | Using low hp units is bad because of Armageddon. Trade them for higher hp units. |
Have you seen other bosses? Help me complete this table.
I found two tricks to fight with big bosses:
- Get a Reaper. Reaper causes Plague on the opponent and removes 33% of it's hp.
- Get Gelatinous Cubes. They have the same Maddening effect as Ctulhu and deal 500% additional damage to big opponents so a lot of damage.
Also an advice on relics. In early game you want to prioritize relics that summon units after every fight. Things like Magic Lamp, Necronomicon, Demonologist, Forest Dryad are all good. If you have one of them then always take Summoner. I also took Mighty Anvil every time I saw it and had a lot of bonus damage from it.
