Great advice for a lvl 5 character
I apologize for the oversight.
If you're at Level 5, it's advisable to maximize your Strength and use a Two-Handed Weapon with 2d6proc damage for Cleave.
Power Attack should be turned on.
Don't forget to wear Full Plate armor, and it's also a good idea to use Augment for an additional 2d6 damage.
Having Feywild's Crown of Leaves and Gloves of Tranquility would be useful.
In places with numerous enemies, aim to engage in combat in narrow spaces like doors, and position yourself to avoid getting shot by arrows.
Additionally, refrain from being the first to charge in, as doing so may attract concentrated fire.
It's safer to instruct your hired allies to charge first and then follow up. The terrain can work to your advantage.
