I'm DM in a game running roughly 6 people, and two of which just entered in as magus. My other four regulars consist of a rogue, a barbarian, a wizard, and a ranger. Bear in mind that this is my first campaign dealing with magus so I'm still getting acclimated to the class.
Before the maguses entered the mix I was able to run scenarios with single large targets and it proved a decent challenge for my players, but in the last couple of encounters I've run the magus players were able to make short work of the large target enemies doing what seems like a disproportionate amount of damage relative to the rest of the party.
So disproportionate that it's becoming quite clear that my other players aren't enjoying themselves as much because they're being blatantly outclassed in combat. It also doesn't help that one of the magus characters found boots of speed in a random loot drop.
How do I handle this?
From what I can tell, magus is just a powerful class, but I don't necessarily know if I want to arbitrarily give my other players good items and buffs to bring them up to snuff.
I've also realized that magus is most effective against one body as opposed to multiple enemies, but I am definitely the type of DM who prefers one or two large enemies at the end of a dungeon as opposed to hordes of goblins pestering you throughout.
Any advice would be helpful, because at this rate my BBEG is going to have to have like 2000hp for him to be any amount challenging to the maguses, but then he just becomes an annoying grind for my other players.
