Get kaels accuracy abit higher and focus more on health than offensive stats. Seriously consider hp% chest.
Im on day 47 on my ftp account.
I recently got to a point where i can farm dragon 13 from here on I plan on just doing dragon and leveling. I dont plan on wasting any time on the golem.
I am surprised your team is not further on dragon than stage 13. Since I only have one level 60 and am also at stage 13.
Occult brawler could probaly help you get past stage 14 which is force. Focus on his surviability (mainly health in dugeons) and accuracy. The key to downing the dragon slow and steady is poison damage.
About champions I mostly agree that the team composition suggested earlier will work wonders. I would hold on to kael though.
1. Miscreated monster (HP, accuracy, speed)
2. Tayrel (Defense, accuracy, speed)
3. Mausoleum mage (focus speed, accuracy, hp)
4. Kael (focus accuracy, speed, hp)
5. Gorgorab (focus speed and hp)
For abit faster runs you could try to swap out mausoleum mage for occult brawler and see if it works.
1. Miscreated monster (HP, accuracy, speed)
2. Tayrel (Defense, accuracy, speed)
3. Occult Brawler (focus accuracy, hp, speed)
4. Kael (focus accuracy, speed, hp)
5. Gorgorab (focus speed and hp)
Also make sure to level the gear you use on your priority champions to level 16, it matters.
