Monsters I'm gonna explain come 3 different groups, purely based on the side of the monsters/bosses
Low Blow. Interact, shield slam now have reason for you to use them. does not share same dimishing returns as holy sense these are critical stuns sense bosses are immune to stuns most of the time wel
Large Monsters - in dungeons will preform tank busters. or may have unavoidable attacks or aoe attacks can be stunned or interjected. these things have lot hp its like fightening mini boss. its advance to kill the big ones.. before you deside to pull big, cause these thing show you no mercy these things deal same about damage as if you pulled 4 small groups of monsters. plus not wise to pull big with these if they can take 50-75% with single attack or summon about 10 bees that all have ability to fatal sting. or 10 bombs that all self-destruct. or gaze at you with eye. turn you to stone if you dont look the other way
Medium set monsters - now target a random dps or tank place a debuff known as enfeeble you take 25% more damage from attacks and you deal 25% less damage. healers need to esuna this status effect right away, they also may unavoidable slam placing heavy status on all nearby melee if you pull large monster with 2 many medium if manage get this debuff and healer doesn't esuna it off you. 100% hp gone
Small Monsters - some may have massive damage attacks. can be avoided. or do unavoidable line aoes. or attacks deal decent amount of damage without laying red stuff on the ground. long list nasty abilities that all tanks should keep good eye out for
bosses will have one ability can be stunned. in there rotation. some may have more then 1. allowing these abilities to have function in player vs monster all bosses even savage bosses and primal will have 1 or 2 abilities melee or tank dps can stun these attacks do have cast time but unavoidable unless stunned
some bosses may preform faints or fakes. using one abilitiy but it second one you really should use stun on or interject. only times bosses are not immune to stuns is when they preforming these abilities
this is to add some over all challange to tanking and healing . not ruin the fun for people
