Other Clarifications
Defense
The target for Defense, including any buffs, should be 4,200 Defense. This is the level at which champions get the vast majority of damage mitigation purely from Defense. Investing more than this in Defense is not efficient.
Health
Health is significantly less important for Clan Boss battles, but as the difficulty increases you still need to have a certain minimum. A rule of thumb that is used by RAID players is that Health should be 10 times the Defense value.
Speed
Speed is a very complex subject. Having more or less speed than the Clan Boss is neither good nor bad - this is because of the way speed works in RAID. What is important is to learn / understand how to speed-tune your Team to go at a specific ratio towards the Clan Boss. 1:1 ratio means taking 1 turn for every Clan Boss turn. 4:3 ratio means your champion(s) go 4 times while Clan Boss goes only 3 times. And 2:1 ratio means your Team goes 2 times faster than the Clan Boss. Achieving a 1:1 ratio is relatively easy, but the faster you want to go the more you need to understand relationships between speeds of all champions and the Clan Boss. For example, it is very much possible to have some champions to go slower than the Clan Boss allowing the others to go faster and still achieve a minimum 1:1 even with the slowest ones. To learn Speed-tuning the best source is Deadwoodjedi's website and his Clan Boss speed planning tool.
Accuracy
Some people overshoot with Accuracy to feel certain, however, the more one invests in one stat the less of other stats you will have. This means that the correct number is better than a much bigger number. What you need is enough to get the job done and not more. Also accepting the fact that there is never a 100%, there is always a small chance to be Resisted.
The way you can get certainty is with multi-functional champions, which is especially useful for reducing the Attack value of the Clan Boss as having only 1 champion, while possible, may result in the debuff being Resisted resulting in a defeat.
