I think this needs to be updated... Because I can't ****ing tell what is a good weapon upgrade and level to be invaded at the lake despite randomly guessing around trying to find the sweet spot..

I am at level 50, weapon +7/+3 but not having the most success in being summoned for co-op. Any suggestions?

I wasn't quite aware of the "Level Cap" for a long while, i am RL 205 and the most i can get online without my friend is getting summoned as a duelist or a hunter... I wish the cap was a bit higher so i could keep helping people with the same character

Common PVP Breakpoints: 30/60/90/125/150
RL 53 (Invaded by 30-58) (Invades 48-78) / Wep: +7(+3)
RL 81 (Invaded by 56-90) (Invades 73-109) / Wep: +11(+5)
RL 119 (Invaded by 90-132) (Invades 108-150) / Wep: +19(+7)
RL 138 (Invaded by 108-153) (Invades 125-171) / Wep: +25(+10)

incredibly terrible matchmaking makes this worse than ds2
the fact that me at level 150 can't duel with another person at 150 just because my stats are different is so annoying

Nice to know that SL 150 is maximum

These levels are -MY- optimal values to have as much activity as possible as a host or summon. First number is the character level, second number after the "+" is the level of standard weapons. These levels are not for invaders, but if you wish to be invaded, these levels are still good.

21+3 to coop with very low levels, or 27+3 if you want invaders, or 26+3 to be able to be summoned by 40+6, or 28+3 to be able to summon 40+6 ;
46+8 ;
62+12, or 60+12 if you're the host ;
80+17, or 77+17 if you only host ;
100+19, or 98+19 if you never host, also +20 if you want +8 uniques and less gap with those with +25 weapons ;
120/125+25 for official tournaments ;
131+25 for coop activities (note: you won't be invaded by 150 if you're 131).

There are trap levels depending on what you want, like level 21 is vastly superior to 20, and if you're always a summon, level 130 is inferior to 131.

what is the optimal level to be summoned at weeping peninsula and limgrave?

RL 53
+8 normal
+3 somber
There, you can now kill Stormveil twinkers easily. Leave Godrick alive, use the tongue and have fun.
