Cleric is the hybrid tree,though, and a lot of physical & magic Classes work well together, even if it’s just in one direction or indirect.
E.g. Inquisitor allows you to turn monsters into demons and boost holy property damage by 10% with Judgement, which is obviously helpful for Exorcists Rubric & Katadikazo.
Inquisitors Pear of Anguish also count as allies for Gregorate, so by throwing one OH at the enemy, Gregorate will always deal 5 hits.
Druid boosts physical attack and crit rate on Lycanthropy, and has physical crit damage boost on Sterea Troph, despite being completely magic-based.
Same goes ± for Krivis, which also boosts Accuracy (very important for physical skills, since they usually hit only very few times) and physical crit attack.
Aukuras also improves physical attack damage with additional fire property.
And the general buffs are useful for all Clerics, be it physical or magic-based (e.g. Oracle/Kabbalist/Diev/Paladin/Chaplain). With the changes, they are probably going to expand this and make certain Classes more interesting for specific builds.
And since as a physical Class you’re forced to use mace, which has magic attack on it in exchange for being exactly one level cap value of same-tier gear below the specified weaponry (i.e. for legendary items a level 400 mace has ± the same attack value as a level 360 sword and same magic attack value as a 360 rod) it’s not so unreasonable to go hybrid.
Yes, you lose a lot of base stats (INT/SPR/DEX/STR) and thus quite a bit basic crit attack and attack, but in exchange you can deal with the primary enemy races out there, demon and brute (which each have a strong defense against magic/physical attacks and are weak against the opposite attack type).
It also makes playing more enjoyable since you get skills for both the close range, far range, single target and multi-target AoE.
On Monk it’s very useful if combined with Sadhu, as you can combine OOB with Iron Skin for ± 40% physical damage decrease, evasion rate increase & knockdown/knockback protection (which Monk lacks). If you can use Double Punch with the body and OOB attacks simultaneously, there is the possibility to attack the enemy from both sides.
Monk also has knockback CC, which can be used to knock enemies away from your body and into the attack range of your spiritual body, which is great to use.
And Sadhu has a %-based recovery on Prakriti, which is very useful for Monk as you’ll probably have a low amount of Healing stat anyway, making the new Heal pretty bad, unless you’re also oracle that can provide a 20 second time frame with Arcane Energy to spam all your Heals until SP is empty and refill the pool again every minute.
