Where: Build ▸ Sacrifice Strike
Portal Spawn enemies arrive through mini-portals that last 10 seconds and spawn 1 enemy every 3 seconds! Focus your Mage and FrostMage AoE onto portals to destroy them early for +28G. Every spawn you kill earns +6G — act fast before the portal floods you!
Where: Fight ▸ Portal Spawns
Phantom enemies split into 2 ghosts with 40% HP each when dropped to 40% health! Destroy all phantoms before any one reforms for +20G. Burst DPS units like Berserker can kill them before the split triggers — watch your damage output!
Where: Fight ▸ Phantom Horde
Your Mage fires an Arcane Barrage on every 10th cast — 4 bolts hitting random enemies for 80% spell damage each! If all 4 bolts strike the same target it triggers a BURST: instant kill on targets under 30% HP and +20G! Stack Mages for constant Barrages!
Where: Build ▸ Arcane Barrage
Bone Shield enemies absorb 3-5 hits before taking any damage — your DPS is wasted until the shield breaks! Use Paladin: holy attacks strip 2 charges per hit. Break within 4 seconds for +18G fast-break bonus. Always deploy Paladin against bone shield waves!
Where: Fight ▸ Bone Shield
A Mimic has infiltrated your formation — disguised as one of your own units! Deploy Warden to reveal mimics on contact. Kill the revealed mimic within 5 seconds for +20G — they only have 1 HP once revealed. Ignore your Warden's alerts and the mimic escapes!
Where: Fight ▸ Mimics
These enemies cycle through Fire → Ice → Lightning elements every 5 seconds. Match-killing them (with a unit of the same element) deals 2× damage and earns +16G! Non-matched attacks deal half damage — watch the element indicator above them and position the right units to intercept!
Where: Fight ▸ Elemental Shifters
Your Paladin can now execute any enemy below 20% HP with an instant-kill Divine Judgment! The judgment also unleashes an AoE holy burst dealing 50% DMG to adjacent enemies, and each execution earns +13G. Chain judgments across clustered low-HP enemies for massive gold gains!
Where: Build ▸ Divine Judgment
Volatile Bombers sprint toward your castle — kill them before they reach it or face a massive AoE explosion! Kill in the last 3 road tiles for +20G (maximum danger = maximum reward). Fast single-target damage is key; never let them close the gap!
Where: Fight ▸ Volatile Bombers
Your Support unit now projects Gravity Wells — slowing all enemies in a 3-tile radius by 40%! Slowed enemies take extra time to reach your castle and are much easier to focus. Kills of slowed enemies earn +8G. Place Support near enemy entry points for maximum well coverage!
Where: Build ▸ Gravity Well
Your Water Cannon now fires a massive tidal wave every 15 shots — pushing ALL enemies back 3 whole tiles! Enemies knocked completely off the path are eliminated for +10G knockback kills! This resets enemy progress and lets your towers deal extra damage while they re-advance. Devastating near chokepoints!
Where: Build ▸ Tidal Surge
Archer and Ranger units now shoot ember-tipped arrows every 8 attacks, marking enemies with burning embers. Marked enemies take bonus damage and every marked kill earns +10G bonus gold!
