[3.13] (League Starter) Konsta's Crit Ice Crash Slayer - 3-6m Sirus DPS, huge AOE, permaleech

+Good DPS on budget gear
+Good survivability
+Cheap gearing...
+...but also immense scaling trough more expensive gear
+Huge oneshots, freeze bosses
+You feel so manly after playing this that even your beard grows a beard

-Cannot run "elemental reflect" maps
-"No leech" maps are dangerous
-Slow attack speed (~2.2) will get you trouble from time to time

We pick slayer ascendancy as the permanent leech ("Life Leech effects are not removed at Full Life") trough "Brutal Fervour" node is very strong defence mechanism. If you have around 6K life, you'll leech ~2.5k life every second even when not hitting enemies. This means that unless you get oneshot, surviving even tighter situations is very easy. Another big reason to pick slayer is the stun immunity. Single this build attacks slowly, we don't want to get stunned on mid-attack. In addition, slayer provides huge AOE boost (up to 50%), bleed immunity, good damage boost and accuracy.

Offense:
-2.3 million Sirus DPS with realistic starter gear, no bullshit POB warrioring
-6.7 million Sirus DPS with realistic end game gear
-Huge Ice Crash radius (45) for nice and smooth clear
-Huge single hits, able to freeze even map bosses
-Easy to cap accuracy

Defence:
-6k life with realistic starting gear
-2.5k life leeched / second
-Fortify

Note that the end game gear & tree can be further optimized almost endlessly based on your budget. The end-game gear in POB is somewhere between 10-20 exalted orbs, depending on league prices.

Leveling Tips:
-Edge of Madness is great leveling weapon until you can wear Terminus Est
-Pick Vaal Pact only When you get your second ascendancy (Brutal Fervour)
-For easy Labs, 1. remove Abyssus and 2. Buy a Writhing Jar. Your leech from killing the worms allows you to tank all the traps.

On this section I will propose both budget and more expensive options. Every piece of gear can be replaced with rare, so don't worry if you cannot buy the exact piece.

Helmet:
Since this is a crit build, Abyssus is best option for both budget and high-budget version. If you have extra currency buy one with "15% of Ice Crash physical damage gained as extra cold damage".

Weapon:
Basically any 2H sword will do. Terminus Est is very cheap and will carry you easily to T16. Voidforge is 30% more damage (but it's hard to cap crit). Best option is rare 600+ pDPS Exquisite Blade.


Body Armour:
Before reaching maps, Tabula Rasa is ok to start with. However after reaching maps or even before, you want to wear body armour with life. Belly of the Beast is good budget alternative. More expensive options include rare chest chest armour with flat crit chance and life, Loreweave and Kaom's Heart based on your own preferences.


Gloves:
For gloves, best in slot are rare gloves with Life, Resistances, Attack Speed. For high budget look also for "Chilled enemies take X% increased damage"-temple mod.

Boots:
For boots, best in slot are rare boots with Life and Resistances. Movement speed is not needed since we'll be moving with leap slam. For higher budget alternative, look for mod "You Have Tailwind if You Have Dealt A Critical Strike Recently"

Rings:
Rare rings with life and resits. For higher budget version get "Mark Of The Elder" and Shaper ring with "Curse Enemies with level X Assassins Mark on Hit"


Amulet:
"Carnage Heart" is solid starter amulet for the build. For more an update, you'll want to have rare amulet with Life, Crit Multi, Resists and Flat Physical Damage.


Flasks:
Life Flask (+freeze removal mods), Lion's Roar, Wise Oak (make sure that your cold resistance is highest), taste of hate, Atziri's Promise.

For more expensive option replace Atziri's promise with Bottled Faith.

Fortify can be either used in Ice Crash links for 100% uptime and better survivability or movement links for slight damage boost.
