Hi, this is a quick and easy guide on Invention when you finally upgrade to tier 80 armor (Nex or GWD2) and tier 85/tier 87 weapons.
You've just spent ~50m on gear and are left with a small cash stack, what perks should I use on my weapons you ask? Well here's a guide for you!
I strongly recommend having 99 Invention for access to the best PVM components. 74 Invention is the bare minimum I'd say.
Higher Invention means getting rarer perk combinations is more common. It may end up saving you plenty of time/money.
Weapons:
Mainhand: Precise 5 (7.5% dps boost)
Precise 5 is from 5 Armadyl components. Get these by disassembling warpriest of Armadyl armor (1 component) or 2 augmented Armadyl buckler (level 9).
Overall cost: 0 (with 5 warpriest) or ~6m for 8 Armadyl components
Alternative Mainhand: Precise 2 + Equilibrium 2
Precise 2 Equilibrium 2 (or P2E2) is obtained from 5 precise components. Get these by disassembling bows (strung or unstrung). (6% DPS boost)
Unlike Precise 5, P2E2 isn't guaranteed. You may need just 5 components to get it first try, or 150 components to get it on the 30th try. Typically should cost you ~500k (I suggest going for P3E2 instead, little more expensive but worth it!)
If you get Precise 3 Equilibrium 2, use that instead. It's slightly rarer but gives about the same damage boost as Precise 5. (7.5%)
If you get Precise 4 Equilibrium 2... praise RNG gods, it's 1/1411 with 120 invention + boost. Typically costs 400m+ to get. (9% DPS boost)
Offhand: Scavenging 2 + any positive perk (either nothing or scavenging. spendthrift will cost you ALOT of money and antitheism disables protection prayers)
This is just a suggestion and will not increase DPS in any way. It will merely save you money in the long run by gathering components as you PVM via slayer, bosses and more. Sofar I've saved the best part of 50m with Scavenging 2. If you get very lucky you can get Scavenging 3.
To get Scavenging 2, use 5 precious components in a weapon gizmo.
Preciouscomponents are gathered easiest/cheapest by disassembling Rings of slaying.
If you're too lazy to make rings, disassemble diamond necklaces or diamond amulets.
Alternative Offhand: Aftershock 3
This gives about a 3.5-4% DPS boost.
Made from 5 Ilujankan components which also requires 2500 Zaros rep at GWD2 (making a guide on rep shortly, will be linked here :) )
Get this by disassembling Dragon Rider Lances or Zaros Anima Core armor augmented and at level 9.
Will cost you quite a bit, I suggest sticking to Scavenging 2 til you're at a higher tier of PVM before going for these perks :P
Aftershock 3 works as, for every 50k damage you deal you deal an additional spike of ~120% damage striking your target and everything around it. Better idea to have this on a mainhand weapon as if you remove it, it resets the damage counter from up to 50k to 0.
Alternative Offhand: Equilibrium 3
This gives about a 4.5% DPS boost, but do not use if you have Equilibrium 2 on your mainhand weapon. Only if you have Precise 5.
Made from 5 Rumbling components.
Get this by disassembling tectonic armor or raids armor augmented at level 9 or Drygores augmented at level 9.
Like Aftershock 3, this will cost you quite a bit, I suggest sticking to Scavenging 2 til you're at a higher tier of PVM before going for these perks :P
If you have a 2 handed weapon, put mainhand and offhand in the 2 slots on the weapon. Dual wield have 1 slot each.
Armor:
Body perk 1: Crackling 3 + Mobile
Crackling deals extra damage every 60 seconds. Is about a 3-4% DPS increase.
Mobile reduces surge/escape cooldown by half. It is probably the most useful perk non DPS wise in the game. It disables earning adrenaline from movement based abilities as a minor downside.
It is made with 4 explosive components, 1 subtle component.
Explosive components come from Hand cannons. By default they give 7 components always. Hand cannons are typically 700k, meaning explosive components are 100k each.
Subtle components come from bladed salvage items. These are quite cheap.
This should take about 20 tries to get Crackling 3 + mobile. It may be cheaper (but slower) to get Biting 2 + Mobile.
Body perk 2: Biting 2 + Mobile
Biting has a 2% chance per rank to force an ability to crit. With biting 2 this comes to a 2.5-2.7% DPS increase.
You can get this with 4 direct components (blunt salvage items) and 1 dextrous (shortbows) or 1 subtle (bladed salvage items).
If you have Mobile already with Crackling 3, do not worry about Mobile with Biting 2, it doesn't stack. Make sure you don't have a negative perk as your secondary.
It is much faster to get Crackling 3 + Mobile, but it is much more expensive.
Legs perk 1: Impatient 3
Impatient gives you faster adrenaline building. It is probably the most important armor perk. When it activates it gives 3% extra adrenaline (11% on an ability), it has a 27% chance to activate at level 3. Essentially means 8% faster adrenaline than usual (if my math is correct and something seems wrong). You'll get your ultimate abilities 1 attack sooner than normal on average.
Get this with 5 Zamorak components. Disassemble Zamorak mjolnirs for these components. It may take 1 or 2 attempts, costing 2.5-5m with a chance of getting Devoted aswell.
Legs perk 2: Enhanced Devoted 3
This perk is amazing for tanking damage, it has a 14% chance to give you the devotion effect (protection/deflect prayers/curses have 100% reduction) for 3 seconds. This just ends up saving you plenty of food.
The best way to get this is 5 Faceted components.
You get these by disassembling crystal items such as crystal teleport seeds, which I *very* highly advise doing.
Killing the elves at Llyeta will yield a chance to drop a uncharged crystal teleport seed. Filling an inventory will take up to 20 minutes. Take these to the Ithell clan in Prifddinas to get them charged at either Eluned or Islwyn (changes to Islwyn after a quest).
Then disassemble these seeds for 1/3 chance of getting Faceted components.
Happy bossing! Hope this guide helped you find what you were looking for :P
