Still going with the same CON build, you don’t need INT’s sustained output in PvP anyway.
We’ll have less HP (i think) to work with yeah, but remember- the same goes for everyone.
Get a feel of your output first, if you think you can wait 27s before killing mobs, get Nga.
If you have decent enough matk and you can kill mobs way faster than that, skip Nga.
Getting Kundela is probably ok if you have the points to max it.
