Maxing out heroes

Generic advise

It is usually best to concentrate on leveling one rainbow team at a time. Only level heroes with same color heroes for maximum hero XP and skill rolls.

I do two rainbow teams at once but I prefer attacking depth - and color stacking - over raw defensive power.

RT11

I love Extra low cost ( RT11 ) training. No items needed and highest Hero XP per recruit ( even if it is very very slow ).

But other prefer less Hero XP but faster ( see notes )

Alchemy Lab

What I find very interesting is the upcoming Alchemy Lab. If you need swords, kits ( backpacks) and Rugged clothes to upgrade your 2* ascension items to 3* / 4* ascension items, then individual players will have to decide if they need hero XP faster or 3* / 4* ascension items faster.

First rainbow teams

I am a big fan of 1x rainbow 3* 3.50 team then 1x rainbow 4* 3.60 team ( see notes )

4* 3.60 heroes

If it was not for emblems, I would use only 3* 3.50 and 4* 3.60 heroes. They are the most cost effective, versatile, available and useful heroes.

Hero XP and deep bench

I am also a big fan of getting 3x rainbow 4* 3.60 before spending any 3* ascension items to get a rainbow 4* 4.70 team ( see Notes ).

Multiple rainbow 3* 3.50 / 4* 3.60 teams are cheap, versatile and useful for color stacking - Empire’s hidden buff.
