-How afects the atribute in the pets?
-If a RB get debuffed by gloom how afects?
-Wich does more damage perma marks or transform? (about sumoner+pets damage not about party ofcse more with marks bcz debuff)
- No effect
- If You are having Grim Reaper summoned and using their skills, it increases their damage, because Gloom lowers the RB's m.def
- It depends on the RB actually. If You are killing Rb with low p.def or he is debuffed (-50% p.def,+45% crit dmg) in some cases transform is better. Lets say Your mark does 400dmg/s (it depends on enchantment level too) So 4 marks gives You +1600 dmg/s. You need to measure what dmg Your summon does to RB. Most hight level field RB's have hight p.def, so You are doing like 3-5k dmg/each pet/per hit. With scenario like this marks+ link is way better than transformation. In case You are killing RB's with lower p.def, like instance RB's and Your summon does like 20k+dmg/per summon/per hit, it is better to cast transformation. Lets say Spirit Of Naviarope usually gives my summons +10k p.atk and if we are talking about party, with BR You will have +20k p.atk and etc.
So, You need to examine the situation You are in to and decide which tactic You want to use. From my own *kitty lazy bastard* experience I prefer using transformation and *lazy mode* aka Defence Mode most of the time. :D
