Is there any way to have like a top 3 rewards a top 10 & participation rewards?

[FireKiller258]

So I want to do a Boss Event on my 1.12.2 server. But I want there to be a top 3 damager rewards & a top 10 rewards but with worse rewards for the top 10. How would I be able to do that & add it in like this. Have it like it has a top damage dealt with players 1-10, 1-3 top damagers being the same reward & 4-10 top damagers having a worse reward? Any way I can do this along with the boss death in chat with the players % of what damage they did. Kinda like cosmic pvp.

Also how do you make bosses not despawn to clear lag

For the rewards issue, you need to manually configure which rewards are given for each damage in a row under Boss Settings > Death > Drops > Player Rewards, it will look something like this:

For the ClearLagg, unfortunately their developers must ignore our entities having Boss_V4 metadata. Bukkit provides a simple check for this using entity#hasMetadata("Boss_V4") so they can integrate without purchasing Boss, you need to ask them.
