The question is simple - what is best to enchant first for ET. I'm looking for both pvp/pve advices.
And I ask for priority too, because my GC, GCM are limited.

well i see u are on L2WS and lower then 82 so start with 2nd class skills

start with life cubic then other skills like tribunal ,shield def skills active/passives,the other cubics etc

arrest, stun, shield of faith, UD (decrase penalty), life & root cubic power, tribunal (modify critical), and elemental heal (+ power) are the most important

thus < btw i forgot about heal,arest and agro lol but he cant enchant 3rd class skill since he is low lvl ;/

where is written he is low level? Even if he was 70+ he is able to make 78 in 1-2 weeks and its better to keep gc for shield of faith than use it for some crap.

I'm 75 and I level rly slow, because I play 1-2 hours every 2 days, but I would keep the GC for later for the best option.

its on his signature ,and on 78 he cant enchant shield of faith too bcz too low rate .. 3rd class skills after 81
