Morytania legs 3 are a reward for completing all the hard Morytania Tasks. Once players complete the task, they can get the leggings by speaking to the Strange Old Man at the Barrows.
Morytania legs 3 cause a new set of bonuses, specific to the new reward, aswell as the effects from the two previous rewards, the
Morytania legs 1 and the Morytania legs 2.
From Morytania legs 1 and 2 Edit
Every time ghasts would normally attack, they have a 50% chance of ignoring the player instead.
Bloom produces double fungi.
Cannonballs are smithed twice as fast in the Port Phasmatys furnace.
You can teleport to the slimepit under the Ectofuntus 5 times a day.
At all times
Razmire gives the player noted planks daily (a choice of 30 normal, 20 oak or 10 teak).
The mushroom patch west of Canifis will no longer become diseased.
Haunted monsters/tools in the Abandoned mine will no longer attack.
For Morytania legs 3 only Edit
Greater chance of getting better keys while burning shades.
50% more xp for burning shade remains.
50% chance of keeping a blood altar teletab when using it.
Each essence has a 10% chance of gaining a 2nd blood rune at the Blood altar (also giving additional experience).
At all times
All ghosts will now talk to you without needing a ghostspeak amulet (excluding the monkey ghost in Do No Evil; you still need a cramulet with ghostspeak in it to talk to him).
Prayer drain while doing Barrows is halved.
+10% more rewards when Temple Trekking, 5% more than with Morytania legs 2
Double runes as a reward from the barrows chest.
Robin will give the player 26 bonemeal and slime in exchange for 26 bones daily, 13 more than Morytania legs 2 (Robin does not accept noted bones). This will require at least 2 trips (unless using a Pack yak) as 1 free inventory spot is needed for each bone; for 13 bones, 26 spots will be needed for 13 bonemeal and 13 slime. Although using the bonemeal for prayer is a common choice, the player could use the daily exchange to get Wyvern bonemeal for making Super prayer potions, and use the slime with demonic ashes.
