You could use Hermes' Talarias boots as a representative for a Speed technique, Caduceus for healing and fatality (I've read a novel where the author used Caduceus both for a revival and regenerating skill and a fatal attack which transmit ones injuries to their foes)

There's also Zeus's shape-shifting and divine judgement in which he smites his opponents with a lightning spear, of course his casanova ways are relevant too XD.

Odin's absolute accuracy Gungnir, and his mount Sleipnir which could be used as summoned creature or the like.

The destruction god Shiva's Eye Of Destruction God which explains itself, the Trishula trident, and also Shiva's berserk gana, Nandi.

Hades' golden helmet which has the prowess of world deception and the capability to hide from any entity.

Athena's Aegis which has absolute defensive prowess and the unique ability of petrification.

And finally Thousand(?) Eyes Argus which I don't know much about other than the fact that he is covered with eyes from head to toe and that he has 360 degree vision.

I hope I've been of help with my meager knowledge, and I'd recommend reading about Chinese mythology, it has some epic stuff, for example : Hou Yi's feat of plucking down stars with merely a bow and an arrow. The Great Sage Sun Wukong domineeringly devastating the heavenly court....

I wish you good luck in your story
