Ok, so i won't go down again about how you must launch hlapex and stuff.
Get to a magister (or master for that matter), activate packet capture, click on "learn skills".
For my example i'll try to learn shadow flare.
It will report this:
6C F3 04 00 00 01 00 00 00 00 00 00 00
Now this is for level 1... Ehw, we don't have the spellbook :(
So, we'll copy the packet and change it into :
6C F3 04 00 00 02 00 00 00 00 00 00 00
02! We jump the level, learn level 2 and therefore don't need the spellbook :D
Even more cool now, you probably didn't know about this but lineage isn't based on a ladder system, as levels of spells aren't about your actual level, but an integer count. Let's JUMP the integer count.
Let's modify our packet again:
6C F3 04 00 00 09 00 00 00 00 00 00 00
OMGWTF! We now have Shadow flare level 9 ! :lol: for the price of only ONE level of the spell :D
Note: It doesn't allow you to get skills above your level, it allows you to buy all upgrades for just the cost of one ^^
