The above bit of 1 prac, spam, then up to 75, well, you can do it but it's tedious. Just dump 2 and be done with it. Set up an action to spam camo after using 1 prac. Practice buffs only once as well (like barkskin, acute). You may find that you can dump 2 into these and still have a full train (depends on your build). Do not practice anything you will not use in PK. No kick, no dark vision, no light armor use, etc. Think weapons, defenses, money skills (ambush, bearcharge, and the like).
