Male Only Challenge Quests

I feel you there I'm in a similar camp. I would suggest using someone with a Gil since his NP does high dmg against servants and the last rounds are mixed class boss rounds with all of them being servants. Just need a reasonably good male rider ( Kintoki or Ozzy are the only I can think of) or maybe someone who can help give Gil stars/boost his crit dmg even further. Gil is strong just not very tanky himself tho so if you somehow had a caster waver that would be ideal to help with tanky/crits as well but he is a 5 star so I know how that is.

- Do not bring Appearance Rate CEs

- Borrow powerful Solo Servants like Cu Alter.

- Field low level Male Servants with taunts(George, leonidas, etc.). Use their taunts to buy turns of no damage. Stuff like Protection from Arrows can be activated early and be halfway off cooldown before Cu Alter even gets attacked.

- Use some of those buffs items. The invulnerability one is pretty silly on Servants like Cu Alter. Or boost damage, whatever you like.

That should be plenty.

Borrow Berserkers. Herc, Cu Alter.. they are males. Also use taunt unite like Leonidas/Geologies, even lv 1 still can taunt enemy.

I used george + kintoki berserker, pretty easy even with appearance rate ce

What people have said. Use Georgios and Leonidas in tandem with a gold berserker such as Herc or Cu Alter. You don't even need Leo and George leveled, you're just using them as meatshields.

Eh I finished that easily with just vlad extra and golden rider boi kintoki.

I was in a similar boat, but was able to easily clear it with Hans, d'Eon, and the provided support lancelot.
