      its faster to kill mosquitos instead of the ticks. from 5-2 take the shortcut bridge and follow it to the end killing everything in the way. i highly recommend a bow or magic so they dont take 10 years to hit. if you have the sodden ring you can take it a step further and jump off the platform and run to the mosquitos at the other end of the cave but i usually dont do it because its too much effort

        A good place to farm Marrowstone. From the 5-2 Archstone double back through the 5-1 Leechmonger boss arena back up the spiral ramp. Fight a few enemies at the top. Then cross the bridge to find 3 Giant Ticks that can be farmed for Marrowstone. You’re welcome.

          Copied from the Upgrades page:

          Fatal Upgrades
          Upgrade weapons with the Fatal upgrade path from +1 to a max level of +5. This upgrade path requires the Marrowstone. The effect of the Marrowstone applied to weapons such as the Dagger, Estoc, and Rapier grants a Critical damage bonus towards backstabs/ripostes. But it also lowers the base damage of the weapon.
