Didn’t know S2 heroes could be got from HA10 been doing that for about 2 months now still got S1 heroes out, S2 pulls must be a 1 in a million return
HA10 will give you 95% another S1 hero, and there is a 5% chance you can get:
Event 5* older than one year
HOTM older than one year.
I believe if you tap on the tooltip in the HA it will show a list of what heros you can get at the special rate. It’s similar to the 5% chance of a S1 5* in TC20
But that 5% chance it comes once a week in HA 10 compared to once every two days in TC 20. So chances to get something good from HA 10 compared to TC 20 are 3.5 times worse.
Excellent point - however as someone who’s still missing many S1 heros, a “good” outcome for me isn’t just that 5% drop of special heros. We are definitely off topic here though so I’ll leave it there.
