We need a more difficult mode

[Extaziii]

Thought, make same rag waves copy pasta in Nightmare mode with certain bonuses.

3x the HP
2x the Damage
2x increased armour
3 wraiths spawned chances increased
Instead of 1-2 tricksters spawning when wave start make it 5-6-7 = so people are focused to not die, go on corners, fences.
XP kept the same maybe tweaked a bit.
