put the prioryty of win process l2.exe to high and u should have this same effect
offcourse the effect of workin game animation not in client side but whole idea of speeding it
1. U need necro or other summoner class
2. exp to 80 lvl
3. Summon & buff your pet (not strider or smth coz it will not listen u to much difference with lvl)
4. Take rebirth with summon u will be 1 lvl but your summon is still 80 lvl u will gain exp if he will kill mob.
