Anything more than 3 players is uncommon..
>full heals
For both the co-op'ers and the invader. Aside from being a boon to FP-reliant builds
>summon spirits
Which don't deal a lot of damage and are easily dispatched. A lot of players also don't summon these at all, I don't know why.
>unscaled
This is actually a massive buff for the invader. Very few people are playing through Seamless with their level 200 friend because, surprise, it ruins the game when your level 200 friend isn't downscaled to play the game for you "fair and square".
Seamless also has other advantages: co-op'ers rarely use great runes, so as an invader with a steady diet of rune arcs you can always have either 40 fucking free levels at low levels or 30% extra HP at high levels. Also Seamless' matchmaking formula is FUCKED. As opposed to vanilla Elden Ring where you almost always invade upward, Seamless tends to match you with players who are at a lower or equal level. You can confirm this by turning on the option that displays players' levels. It also has no blues, thank fucking god.
I have a ton of hours in both vanilla and Seamless. Vanilla is FUCKED at every level, even low levels after the DLC. Seamless is way, way more relaxed.
