PVM= Leech gear, MVP= specialized gear(gear that increases your damage output, check out temporal boots). I would start with the leech gear first, then move on to the specialized gear.
The leech gear setup for a bruiser(melee) royal guard looks like this:
hunting spear/long horn/battle hook with 1 hunter fly card
Rosa shield with racial card or elemental card
rideword hat/pirates folly(cheap alternative) with marduk card
Orleans gown with earth deleter card
nyds garb with raydric card
variant shoes/valk shoes with an experience card
blinker/ dark blinder
umbala spirit/chewing gum/spare card
3 clip/eye stone ring with 2 hell poodle cards + 1 creamy card
Rideword hat is superior with 1 hunter fly card since you don't have the chances of two going off each time you hit a monster, so your HP leech will suffer with a Vanargand Helm. I also know from personal experience since I use this setup, in fact I'm currently mob farming vanberks using overbrand, moon slasher, and shield spell 1 for 2-3 hours straight. The only consumable I use is meat, I receive 20% more damage because I'm using an Am Mut card, and I only heal when I'm in the red lol. Additionally you can substitute the nyds garb for an incubus pet, or the hunter fly card with a succubus pet.
A Rune Knight setup is slightly different if your going for a two-handed weapon build:
Violet fear/Tae Goo Lyeon with 2 hunter fly cards
Vanargand helm/pirates folly(cheap alternative)
armor of naga with sky deleter card
The rest is pretty much the same, the main difference as you can see is a 300 mil helm that is currently way over rated lol. Basically since you don't have any racial reduction and two weapon slots instead, it's better to wear a Vanargand which will significantly increase the chances that both hunter fly cards will go off. Also since Vanargand has an extremely high sp proc. with Nyd garb you won't be needing the earth deleter card so swap that for a sky deleter card which will give you even more hp leech and with that you should have no problem surviving without racial reduction. Also you won't need Orleans gown or a phen card on a Rune Knight unless your using bowling bash(last time I checked this skill was interruptible), since pretty much every other skill is uninterruptable.
