The actual effectiveness of either flask varies with how much base armour and armour modifiers you have.
Basalt vs granite flask.
Can only hold charges while in belt.
It depends on the size of the hits you want to tank your current armour stats and what other sources of phys reduction you already have end charges aa etc.
Basalt is volcanic or extrusive forming at the surface while granite is plutonic or intrusive forming beneath the surface.
Granite is superior to basalt for weaker enemy hits.
The key difference between basalt and granite is that basalt is mostly occurring on ocean floors while granite is in the crust of the earth in all continents.
Can only hold charges while in belt.
The specific heat capacity of granite is 0 79 kj kg k and that of basalt is 0 84 kj kg k.
The reliability of 20 additive pdr.
Granite flask granite flask lasts 4 00 seconds consumes 30 of 60 charges on use 3000 to armour requires level 27 right click to drink.
The cloud is nice for bosses but you really shouldn t be trying to face tank bosses with evasion.
Jade is in my opinion always superior for evasion builds due to keeping the benefits while moving.
To be perfectly fair i overestimated granites against completely ludicrous single hit damage.
Basalt is common on both earth and other solar system bodies such as the moon and mars while granite is only common on earth and rare elsewhere in the solar system.
Basalt is superior to granite against spike damage.
Basalt granite with inc armour during flask effect granite is better in generall if you have low base armour since the scaling with armour is better on the lower armour ratings basalt is the better choice when you already have high base armour.
Basalt and granite are two types of igneous rocks.
Duration 4s with 100 armour.
Earth contains three kinds of rocks namely igneous rocks sedimentary rocks and metamorphic rocks.
For low armor chars.
Basalt is mafic while granite is felsic.
Refills as you kill monsters.
As a general rule granite will be better against multiple smaller phys hits but basalt works better against giant slams.
If you take a literal one shot the basalt is in fact notably stronger.
If you activate the jade flask initially you get a 20 movement speed bonus.
Theres no definitive answer.
