I will post several general builds and discuss changes that could be made. Always try to feel out builds for yourself as it makes you a better player Pet Forest and lets you make customized changes when you need to.

Powerful Blow Tree: You may notice the excessive use of rubies that are blank or unnecessary (Take Cover). You can remove this WHOLE bottom-right area and use it elsewhere or pick and choose between more stamina or health. If you require more damage output you can instead get the other Powerful Blow ruby across the blank space or move up and snag the Finesse/Expertise rubies.

Charge Tree: There are not many changes that could be made. You do not need to make the branching-off to the right from that Finesse ruby if you do not want to, but Arm Breaker, Reinforced Skull and that extra Strength ruby can come in handy.

Slash Tree: There is a good amount of customization that Pet Forest Gold can be made in this tree. If you have trouble keeping aggro from certain members you may choose to pick up points in Stalwart Defense or you could break off from Cruelty and pick up Inciting Shot to pick up more monsters. If you need a short-term CC you can move down and pick up Intimidation (although I do not recommend it).
