monster damage types

Greetings,

How do i find out the damage types of certain monster attacks?
Is there any website with information for all monsters ?
I would like to know the damage type of the projectiles from the miscreations in lunaris temple.

Should i just assume its physical, so poping a granite flask with many on the screen will help ?

they use Attacks - 50% phys / 50% fire

wiki explains it rather good.

special thanks go to Iamacyborg for maintaing this site.

@Ludvator
thank you, but where can i look that up or how to find out that there is fire damage in it too ?

http://pathofexile.gamepedia.com/Damage_Types ist just generic info and not monster specific.

the knowledge comes from experience, observation and testing. There is no official information. GGG likes players to figure some things out themselves. Furtunately, many players like to research and test. If I remember correctly, raics has gathered information on some monsters damage types, he posted it here in the past but I think he would share his knowledge if you pm him (you can find him in many threads in this forum section)

some information can be found on wiki, see Spectre choices article
