The wiki info is more an overview and how it works.
The Pro boss event guide for score boss weeks is more for already a bit developped players
Easy how to "score boss" further down this page ▼
Basically events come like shown in wiki in 2 possible forms boss/level event score week and science/influence score event week.
The bosses change every 2 weeks so whatever one of the two you pick, you should know if you get a chance on the next week again as boss/level event weeks are easier for starters.
Work on your dpc and skill prolonging artifacts to have them all maxed before you attempt for higher ranks in event weeks with score boss!
Same goes for science week, wait to aquire event heroes until you have at least space or better star and soul heroes!
The farther you come on the hero aquise you will get more and more heroes that give boost to rating, and influence.
Know your score bonus by adding up the hero influence boosts or rating boosts!!
This list will help you see what current boost you have if you tick on which heroes you currently own. Its a bonus calculator on russian wiki, so use chrome browser to get auto translate!

It is important to prepare and know what estimate you have over the week, with your daily effort throughout the week or to see if it is worth to invest via bottles at the weekend. Most people try to hold position early so it could be worth trying doing the maths to see how many bottles you will have to spend total, by asking global players which score the rank you want to get to, currently is.
if you are a new player i recommend to go for Lgnath the wraith first.
It's a reviver and helpful in Siege and clan mine.
Halloween and christmas there will be special heroes that aren't normally in the rotation, so you better put some bottles aside already ^.^
All other heroes are listed in wiki
So the importance of paying science and doing arenaor battle lots of score bosses not only for your own but for your clans sake should be clear, there is a ranking for clans influence (overall) and we do not know in which part this ranking benefits the clans yet. BUT, the weekly ranking in event is important for your clan as it will give the right to participate in clan mine fights when it reaches the TOP 100.
So it is in every clan members interest to participate to the best of their time to push the clan up that list.
