Rot
Rot Infection
Rot Infection by monsters
A Rot infection is lasting damage that you catch when receiving any kind of rot damage. The burden of your infection is defined by the rot damage you received. Rot starts with an initial damage and keeps increasing every 15 seconds until reaching a maximum.
Below's a list of four different rot infection scenarios:
Rot: +2 damage up to 20 Strong rot: +3 damage up to 30 Aggressive rot: +4 damage up to 40 Lethal rot: +5 damage up to 50
Getting hit with 35 rot damage results in Strong rot: increasing by 3 damage every 15 seconds up to 35 damage total. Depending on the amount of rot damage you take your infection can increase. Your Strong rot can become Aggressive rot and Lethal rot. 10% of your damage dealt will be converted in additional instant rot damage to the enemy.
Rot Infection by Promethium weaponry
Promethium weapons and arrows apply rot damage. They provide a stacking effect on every third hit instead of a flat application on special attacks. Meaning that continuous hits with promethium equipment will increase ticking rot damage. This goes up to a maximum value of 100. This means that you can stack rot effects with multiple people providing the enemy is not immune to rot.
Rot protection
Antirot potions
Drinking any antirot potion (regular or super) grants immunity from rot infections. It clears all rot infection damage ticks and prevents you from catching it. You also gain a 50% rot damage reduction when under the effect of antirot.
Prometium equipment
The 6-piece set effect of promethium also grants 50% rot damage protection but it DOES NOT grant immunity to rot infection. In combination with an antirot potion you can get a total rot damage reduction of 75%. The effects are combined multiplicatively: 50% from antirot potion is increased by another 50% from promethium --> 75% total.
