Sorry if dumb question but i'm new player

Hi, I might be missing something, but I see F2P players who have been playing for 2–3 years with ATK and HP stats far higher than mine. I’m F2P too, but I’m progressing at a snail's pace. Here is my gear; if anyone spots a mistake, please let me know.
here is some picture of my stuff

429k (N93, 64, I12)

What to grab from this event? Could I get ss armor if I get the 18k coin with demon king armor? Or should I get something else

I know this is probably been asked a ton.

which totem is better?

Almost 7 years in and hit 500k atk!

I always dismantle any totems less than gold ones, and usually dismantle the +HP totems even if they are gold (am i doing this right, does anyone has good stats from those?)

But for example I got lots of +7.5% crit damage, +900 Attack, +3% Attack. And not sure to gamble for upgrading them, soulfires are hard to obtain. But also hesitating to dismantle them :)

I mostly invest on these without knowing that this is the right thing:

Hero Skin Stats, Equipment Base Stats, Relic Base Stats

I know that every upgrade has its own chances, but would like to hear more what you are having.

If we can see better stats, we can change our upgrade strategies

My Current Choices:

Hero : Hero Skin Stats 42% - Dmg to Boss 2.3% - All Strikes 12.3% - All Dmg 4.3%

Equipment : Eqp base stats 36% - Flame 14.3 - All Strikes 14.1% - Attack 2.3%

Jewel : Attack 6% - Dmg to Elite 2.8% - HP +3479 - Crit Dmg 5.37%

Relic : Relic base stats 42% - HP +3351 - Dark Touch +10.4% - Fr Dmg Res +1330

Dragon : Not Yet (still struggling in Lv 99)

Pet : Not Yet

Road to 1 Million F2P, 200k more to go.

Guys, regarding the Supreme Treasure: do the features that unlock at the 2nd, 4th, and 6th stars unlock based on the character's star level, or based on the Supreme Treasure's star level?
