By the time we teleport from the ship I have used up my swallow and thunderbolt.
I have tried samum and dimertium bombs. They do no damage.
I have tried yrden and igni but still die over and over again.
Those blue beams he casts come too quickly, quicker than I can roll away.
First play through was easy but the NG+ has made this fight impossible, for me at any rate.

It's a known bug. See here: https://www.gog.com/forum/the_witcher_3_wild_hunt/eredin_fight_bug

In my case, after a while we teleported and he was receiving damage normally.
