If you're low on money, this is my go-to build for wilderness PK. Alternatively, you can replace the blessed spirit shield with a mage's book.
If you're worried about switches, and also don't want to risk much, here's a tele blocking build for you. This is probably the easiest build to use in my opinion. If you don't have a firecape, use an obsidian or whatever you have. A dragon dagger can replace the granite maul, but you lose out on around 6 damage.
Now this is my main deepwild build. It is quite expensive so I don't recommend using this if you are worried about money. I sometimes swap the ahrims for zuriels.
This is my revenant caves build for when I'm in and out, this is a risky build so I only use this if I'm making a single pass or I've already scouted caves. I focused on dps here, and it's not good for a fight against a PK tribrid build.
Here's a more affordable main build for deepwild. If you don't have firecape as always you can swap for obsidian or etc.
This is a lower cost build that packs an insane punch. I like using this a lot, but it's pretty situational. You'll need the firecape & berserker ring for this one, it's not something I'd swap out.
