summoner dps how to do it

[Sunako]

The extended buffed dots + extra Ruin casts adds about 500 Potency to the opener.
This is greatly increased by time sensitive skills such as Battle Voice Foes and Trick attack, as well as doubling the damage of a Poison Pot with Contagion.

How quick Garuda attacks at the start (ranged) + Foes offsets the Potency of Ifrits Enkindle/Extra damage.
Once the pet buffs are off and the slash/blunt debuffs are up you definitely want Ifrit out though.

You will only gain 1 extra ruin because your swiftcast summon III + (delay after summon your pet may lose one attack as well) will burn one of your gcd. Ifrit enkindle is magical damage as well so it will get boosted too from foe. It is pretty hard calculate accurate dmg difference between ifrit and garuda in 20 second(during cooldowns are up) but I test myself today and after 1min dummy fight ifrit damage is around 60+ dps higher than garuda so cooldowns affect lot more for ifrit than garuda + i did not waste gcd for the contagion. 60 dps in 60 sec is 3600 more damage. Can contagion alone cover that damage? Without cooldowns, gap between ifrit and garuda is not so high anymore.
