Yep, it sucks.
Trials of Fortitude is challenging, and requires substantial coordination of a team to kill Vivica, or usage of Battle Items that you probably don’t have yet, unless you’ve gotten a Forge to Level 16 so you can make Dragon Attacks.
That’s how all of the challenging content in this game goes — it’ll take you months to be able to beat all of it. You’ve made progress coming this far, and you may well be ready to beat it the next time it comes around in 5 weeks.
