A mod that takes Old School RuneScape and gives it an HD upgrade from haoxiuyun's blog

It is one of the greatest melee abilities that players can obtain on RuneScape 3, though it requires some grinding to RuneScape Gold get there. Because of its distinct characteristics and activation method that make it difficult to beginner players and is more appropriate for those who are familiar with the Revolution combat system.

Blood Tendrils is the best melee combat feature accessible on RuneScape 3 and is not unlocked until a player is deep into the middle-game. The ability will require 75 Attack to activate, and is one of only five bleed abilities that are available for melee. It will result in the best swordfights that are available in the battlefield.

The targets of this ability can be able to take anywhere from 36 percent to 180% damage, and also bleed effect. The caster will also receive bleed damage. So, it's important for players to not use this when their HP is low because the power could end their lives.

Runelite HD is a mod (made by a single person who is 117) that is a mod that takes Old School RuneScape and gives it an HD upgrade. In 2018, Jagex were issuing legal threats to mods similar to these, claiming that they were copyright violation. However, these appeared to have disappeared when Jagex gave their blessing to one of the first Runelite.

But earlier this week, just hours before the improved Runelite HD was due for an official release the 117 group was contacted by Jagex in a letter requesting that work stop and that the release be deferred. However, this time the issue isn't due to OSRS Gold For Sale copyright claims, but because Jagex claims they're creating an own HD upgrade.
