I really like that events are starting this year right in the beginning of January. During last couple of years, we haven´t seen the first event sooner than in the end of it (while hitting live servers in February) and it wasn´t anything else than Carnival event - which we saw 3 times already. So glad to see this change in the pattern.
you posted 2 pictures of 75+100% so lets asume right now there are 2 of them and maybe in the future they will be available in the
magic academy. and the explanation is in the picture you posted, it says what it does.
In the silver and gold league you can now get a building of your choice from the old pilgrim’s manor set. While I appreciate the chance that people are able to get missing buildings from previous events, I think this option should be more accessible than just to the top 5% of players. I liked the way how to obtain the old phoenix artifacts - converting the new artifacts into old ones. This way people do have to pay a price for getting the old ones (because it was 3 new artifacts for 1 old artifact, if I remember correctly, so nobody could get a fully evolved new building and level the old one at the same time). But it was an option which was available to everybody.
These times the options to get old event buildings are getting more and more p2w without any chance to get there without paying a really big amount of diamonds (this was also true for the last event).
Vitality surge instant can be used right after the fight in the results window:
After pressing the "heart" button it´s possible to choose vitality surge instants (similarly to boosters when skipping the production) to heal a number of percent (depending on the power of the instant) of squad size. What´s a clear benefit is that this instant gets really powerful in higher tournament enocunters, where the squad size increase a lot and hence it heals many more units compared to the small squad sizes in the first encounters.
It is also possible to use them between the waves of spire battles.
