Demon Portal

Demon Portal
Spawns two (three when fully upgraded) friendly demons that block most enemies and fight them until death. The demons respawn periodically. The Demon Portal trap is placed on a wall block and allows you to choose an adjacent floor block that will then spawn demons.Appearance Abilities The demons block most units (exception, thief, priest, horse) and fight them.

This trap will spawn demons in an adjacent field your choosing. Lvl 1 produces two demons, lvl 2 produces demons faster, lvl 3 produces three demons.

Spike traps will hurt friendly demons with 50% of the regular damage. They will only get triggered by enemy units though. Projectile traps (Dart traps, Bolt traps, Harpoon traps, Inferno traps) will not hurt the demons. Projectiles will pass through the demons. Demons will get hurt by grinders and also block them like regular enemy units would.Strategies Choke Point Blocking Use these guys to trap large numbers of heros in a kill zone, or block the entrance to your pit.

They work especially well in combination with Spinblade Traps. The demons will block the enemy hordes for a while which gives the Spinblade Trap time to reset. Place traps with high damage output before the Spinblade Trap.

E.g. fully upgraded Spike Trap, a Spring Trap (If there is water or lava next to it), or a fully upgraded Slime Trap (becomes more useful in endless mode). Wall traps like Inferno Traps and Bolt Traps should also be placed in the kill zone.

Example setup: The Mechanical Boost consumable trap is useful to shorten the reset time of the Spinblade Trap in this setup.

Because most of the enemies will die before the choke point, it makes sense to place a Slot Machine nearby.

Strong Knight enemies have the ability to kick the demons out of the way. This can be counteracted by creating the setup in a corridor that goes around a corner.Strategy 2 This is a second strategy.Stats 1% reduction to resummon per Gem Level. 5.5 seconds between summon at Gem Level 50 A Demon Portal at Trap Level 3 with Gem Level 50 spawns 3 Demons with 4.11 seconds resummon time.
