Right click to remove from a socket. and Wither are now channelled skills. Unlike other skills, which are used once and quickly finish, when you use a channelled skill, it doesn't finish until you release the relevant button/key. You continue performing the same skill. You need to pay mana repeatedly to keep the skill going. The channelled skill's mana cost must be paid again to maintain it with a frequency determined by the cast time. If you can't pay, the skill will end, just as if you'd lifted the button. Dying, being stunned, and other game mechanics that interrupt the use of skills will cause channelling to end as well. Effects which trigger when you use a skill will only trigger when you initially start channelling - regardless of how long you maintain a channelled skill, it's still the same use of the skill. You need to stop channelling if you want to use it again.
2.1.0	Added to the game.
