Solak is a boss with 2500 HP that drops the supplies to create the best range armor and one of the best ranged weapons in the game.
To get to Solak simply go to the teleporter in the home area, select bosses, and scroll to the bottom. Solak is the second to last boss in the list.
Before we talk about actually killing Solak lets take a look at what he drops and what these drops do.
1. Algarum Thread - Algarum Thread is the key component needed to create the Sirenic Armor
2. Sirenic Scales - Sirenic Scales are the secondary ingredient in creating the Sirenic Armor, also used to charge the armor and the Seren Godbow
3. Seren Godbow Stock and Seren Godbow (unf) - Combine these two to make the Seren Godbow
Solak has 2500 hitpoints and its pretty straight forward, he is also the perfect boss to chill and hang out with friends as long as you have two or more people. You can solo Solak it just takes a little more time and attention.
Gear: The only thing you need is halfway decent magic gear like Ahrim's, Void of any kind as long as you have the mage helm, and any staff. Use blood barrage so you gain HP throughout the fight. (Solak is basically immune to any damage that is not magic damage)
Solak has 3 attacks he uses
Magic: Solak throws a green orb at the player. Make sure to always be praying mage, this attack can hit up to 50's without prayer, but won't hit through prayer.
Ranged: Solak will throw a stone at a player (looks much like demonic gorilla ranged attack). This attack deals minimal damage to the player (2-10)
Solaks special attack: Solak will occasionally jump into the air and throw out a small green attack that will hit a player. This is the only real damage Solak will do to a player and it can hit upwards of 50's, prayer or no prayer. If you are soloing Solak just try to run to a different location when he jumps and you can usually avoid this attack. In a group you can run but the likelihood of him using this attack again on the same person in a row is small.
Once you kill Solak the loot will go into your inventory.
Making the gear
To make the full set of Sirenic Armor you need 5 Algarum Thread and 280 Sirenic Scales
The individual scale cost of each piece is:
Sirenic Mask: 50 Scales
Sirenic Body: 100 Scales
Sirenic Chaps: 80 Scales
Sirenic Gloves: 25
Sirenic Boots: 30
Total Cost: 285 Sirenic Scales
The Sirenic Mask, Body, and Chaps will eventually degrade. To recharge them you need the same amount of scales you used to make them, but no Algarum Thread. (50/100/80)
Seren Godbow: To make the Seren Godbow simply use the stock on the (unf) and select yes in the dialogue.
The Seren Godbow will also degrade costing 100 Sirenic Scales to recharge it. That being said there are multiple 'Skins' you can put onto the Godbow that will make it undegradable. The skins can currently only be bought in the donator shop for 50 Dragonstone Tokens each.
There are currently 5 skins: Barrows, Blood, Third-Age, Ice, and Shadow (left to right)
The Shadow, Third-Age, and Barrows skins are only cosmetic whereas the Ice skin has a chance to freeze your target and the Blood skin has a chance to heal for 1/4th of the damage dealt.
