A regular embrittlement has the same range its debuff can actually stack with the super brittle, so it can simply be placed next to it to achieve the same results. Refreeze is not needed to refreeze bloons. Range from the other crosspath can be made up for in the top path Village.
Since Sun Temples can only accept sacrifices in 3 categories, to optimize VTSG/Temple sacrifices, have two or three 1-0-1-1 temples to cover the entire map, and have the rest of the temples being 1-1-1-0, with the VTSG being 2-2-2-1.Geraldo can also be used, although the differences from degree 100 paragons to degree 76 paragons are mostly minimal. If neither of those two heroes are available, Brickell can be used as a weaker adora that can only buff temples and the VTSG with lower uptime.Ezili would also be quite good due to her ability being able to deal massive damage to BAD bloons, and could even theoretically outperform adora through buying and reselling, although quite time-consuming to do and might not even be affordable if BAD bloons spawn too often.Adora herself would also do a lot of damage, even outperforming temples. Adora is usually the best lategame hero to run, as her Blood Sacrifice doubles the damage of all Sun Avatars, Sun Temples, and the VTSG.A VTSG is preferred, since the mini sun avatars gain massive bonus damage. Due to the fact that paragons do not gain any bonus boss damage, it will have the highest single target damage available.
Use of the Vengeful True Sun God or, at least, the True Sun God is a near necessity.This means that even the Apex Plasma Master, which is weaker than maxbuffed Sun Avatars, is worth getting, since you do not have to take out a stronger tower to use it. Since they cannot be sacrificed, a paragon can be put inside a temple, meaning they take up no effective space. Always get paragons first, and as a high degree as possible.
