pet reviving time...?

is it true if the waiting time to revive on pet is same like our character (300 secs without any revive time reduction)?

 

Yep. Don't let the poor thing die in battle. Nothing you can do to help it up...

 

it's 150 seconds, same as a character with Play Dead lv10, but you can't use first aid on them.

this was tested by having a pet, a character with Play Dead lv10 and a character without Play Dead die at the same time (Pillow Golem's laser beam) and then wait until they revive.

 

and, how about the damage taken? is it work like our character, or it's work like merc?

 

since their def growth is lower than ours and they can't equip armor, i would assume that def/mdef is calculated like it is for monsters, by directly reducing the attacker's atk/matk.
in addition to that, they gain damage reduction based on distance, where they receive less damage the closer they are.

short version:
it works like mercs

 

is that mean, the pet will get high damage taken if the monster attack the pet from 30m distance or higher (for example pillar golem laser)?

 

probably yes
