Want to unlock some skills for free?
This is hopefully common knowledge, but I thought I'd post it anyway - just in case. You can use Balthazar Faction to unlock skills which your heroes can use or you can then use a tome to learn. The Zaishen Challenge can be easily farmed with a trapper ranger to earn a max of 2000 points per 24 hour period. There are some team builds out on Pvxwiki for farming the Zaishen Elite which allows you to earn more points per day, but I'm lazy and the quick and easy trapping works for me. Normal skills cost 1000 points and elites cost 3000 points. You can also spend 5000 points to buy a key which unlocks the chest in the Isle of the Nameless and can net you random useful stuff. Look that up on guildwiki if you're interested. Here's my build: OgATYt7iZa4q5Y5Q5YXK5gLE6AA Superior Wilderness in hat, Sup Expertise, Sup Beast, Vigor (unneeded, just there already), Attunement, all radiant, +20 energy staff. From the Zaishen Challenge, pick Select Mission and pick the Victory is Mine Trappers, any arena will work, let it be random. You don't have to move. When you zone in hit Trappers Speed and run through the traps, hit EoE, then keep up TS and use the traps as they come available. The trappers run to you and die on the traps. Done. Occasionally one gets hung up and comes in too late and starts rezzing. Just die or zone out and start over. Does anyone else farm this with other professions?

Only done this a couple times, and each time was with a trapper as well. However, since I didn't find it very exhilarating, when I want/need Balth faction I usually just do some AB. Thankfully I don't need to unlock any skills, as I purchased the skill unlock packs as soon as they were released. :D
