I add these properties to e.g. my mana flask or some item I'm not going to be replacing anytime soon.
IDK if the resulting leech calculations are accurate, but at least I can see if an item/node is going to increase or decrease my leech significantly.

1000000000000% increased maximum recovery per life leech
1000000000000% increased maximum total life recovery per second from leech
1000000000000% increased maximum recovery per mana leech
1000000000000% increased maximum total mana recovery per second from leech
1000000000000% increased maximum recovery per energy shield leech
1000000000000% increased maximum total energy shield recovery per second from leech

@mahhov

I opened #2550, which replaces the PoE1 leech calculation with the PoE2 rules from the wiki:

"increased amount of Life/Mana Leeched" now multiplies the leech per hit
each instance recovers over 1 second, and faster leech shortens it
only one instance per resource recovers at a time
hits count at most 40,000 damage for leech
the PoE1 caps (10% of the pool per instance, 20% per second in total) are gone

Monster leech resistance isn't in it yet; #1938 adds that, so #2550 references this issue without closing it.

@mahhov with #2550 the "maximum recovery per leech" workaround mods are no longer needed. They won't parse any more, since the caps they raised are gone.
