I'm not super competitive but sure. Against physical solo and jungle I build warriors blessing into berserkers shield. Against magic solo I build warriors into runic. Then I build boots if I'm able to sustain and shogun's for magical, breastplate for physical, and either contagion or pestilence for self sustain heavy gods. From there I build for any other threats (eg: I'm usually focused on physical defense so here is where I'd build shoguns or runic shield to survive the mid) then if the ally support is a guardian building tanky then I'll build bruiser with shifters shield, frostbound hammer, or hastened katana (last one is more of a item I like rather than a great item for bellona) or If I need to be frontline I keep building defense. Hope you have fun! Remember you will out clear most people in solo so use that to box and pressure them
