Path of Exile Guide on Chaos Inoculation
Amidst the forest of nodes that you may have to deal with in Path of Exile's massive passive skill tree, there are the big ones known as keystones that are chosen as foundations to many a character build in the game. One of the most popular keystones is Chaos Inoculation, which is a curious sort that only the brave and the smart can make use of properly.
For those who are not familiar with Chaos Inoculation, it's a keystone that gives the character total immunity from Chaos Damage, but at the cost of health points being reduced to 1. It seems to be quite a big trade off, but there are a number of popular builds in the game right now that make good use of it while doing a lot to make up for its cost. As with most things that come with Path of Exile, it's all about figuring out the best synergy.
Choosing to use Chaos Inoculation gives the player a whole set of problems to address in exchange for its advantages. The reason why it's for more advanced players is because it trades in so much for that immunity to chaos damage, which is indeed a powerful ability. Obviously, your life is down to 1, which means that you're one hit away from death if you don't have anything else to serve as defense. Energy Shield serve as the lifeline for survival, which is where Infused Shield comes in with its 15% bonus to your Energy Shield.
First of all, you cannot use Blood Magic and Eldritch Battery since they're both obviously incompatible with Chaos Inoculation, unless you want to commit suicide every time you cast something. That makes for some problems with resource management, especially if you're primarily a spell caster. You also have problems when it comes status ailments and stuns since you won't have much to work with for gaining immunity to those effects unless you deliberately go for something like Unwavering Stance.
It may seem that other builds not using Chaos Inoculation, especially when considering that Chaos Damage may not be that threatening to some, even if it's still helpful to be immune to it. The loss of HP still seem rather excessive for some who don't know enough about whatever can be done to reduce incoming damage, increase Energy Shield, and whatever Path of Exile items there are that can help bring the build together.
If you are thinking of getting Chaos Inoculation, you must first have some experience in dealing with incoming Chaos Damage from enemies to truly know if it's actually good for your future build. Playing around with it can yield a powerful build that can stand up to the most powerful of enemies, but it also can limit a lot of other options in the passive tree that may be viable in other builds.
You do get tons of Energy Shield though and you won't have to take life nodes in addition to not having to worrying about Chaos Damage. When used right, you'll end up with a character that has 10k or more Energy Shield that can stand up to most abuse and give you more than enough to blast through mobs of enemies.
