Because of these changes (and some previous) there will be some unused effects, that can be used in some other way.

The effects are:

player cant heal (bugged, but can be made into smth. new, flag type effect)
monster cant heal (same)
attack speed 2 (not sure it has potential, but we can try)
constantly lose life (its code was used for passive life'n' mana regen, but the effect is free now)
peril
doppelganger
move 40% life to mana

To give a little explanation on this: in Hellfire they modified some stuff. Armor pierce was changed from random between given numbers to mosnter's AC reduced by specified %. Or of Thieves effect began reducing damage from arrows and spells, too. You get the idea....

Now I'm thinking and looking for ideas on how to modify the above enumerated effects into something that would increase gameplay or improve the game otherwise.

Time to exercise imagination

Iron Maiden - with % bonus like 100 / 200 / 300 - if monster deals x damage to player, it takes back x * % bonus damage

XP progression table will be updated in 1.59. And CLVL restrictions for highrer modes will be again set to CLVL 30+ for Horror, and CLVL 40+ for Purgatory.

But players will have enough time and XP to prepare for Purgatory/Doom: level 30 won't come as quick as before, and level 40 will come approximately as level 43-44 comes now. Leveling further (from 40 to 50) will go smoother than now.

Examples:

u have char with 500 000 000 exp, old 43lvl could be reached with 520 000 000 exp.

If it will be decreased to 300 000 000, for example, you will gain levels for every mob until your exp wont be less than required exp for next lvl.

If it will be increased to 1 000 000 000, for example, your level won't decrease, just you will have to fight 500 000 000 exp on lv42
