I've tested life and found it scales with playercount and is locked in when binding
I haven't tested damage, since that's such a minor scaling and hard to test, but other people testing it have claimed it shows damage does *not* scale with playercount / isn't locked in at binding
Likewise its extremely obvious that bind demon's added +damage being applied to A1/A2 is reset with every game, which is as simple to test as having a char with 1 point bind demon and +99 skills gear and joining games with that gear on/off- it will OHKO everything if you joined the game with that gear on, and do negligible damage with it off.
From my own personal tests, made both offline with similar huge +skills and online with my poorman’s options, I’m also convinced and have the same conclusion as you about those subjects:
Player count / TZ snapshot life of the demon
+skill matters at game start
I have the same hesitation as you about the question “does player count / TZ snapshot the base dmg?”, but yeah… it barely matters since the dmg mostly comes from skill lvl
The one thing I can’t understand yet, and that feels like an important detail, is… can a bound demon be higher lvl than you?
As mentioned above, the life (and possibly dmg) are snapshotted when bound.
But I’ve had conflicting results when it comes to the aura lvl.
Prior to clvl 96, my bound demon with conviction wasn’t always overriding TZ 96 enemies’s conv.
At clvl 96, it did.
Like if the demon’s lvl was restricted to your own clvl (like it is for most pets, except ravens).
But that’s from limited testings, and I know the conviction override can be clunky at times…
Would need to test properly with another aura, like might, on clvl below 96 and 96+ with the exact same gear/stats to see if we do really get +10% ed or not.
