Mines = autotarget walking and blasting. After you play builds like this it can be hard to go back
Mines have no reflect
With pathfinder and some reasonably rolled flasks you can easily get stun, ignite, shock, curse etc immunity or at least resistance. You are also crit immune from your poisons.
Extremely fast - this is preference only but depending which flasks and mods you use you can absolutely RIP. I have a steady 177% movement speed
Great AoE - Bladefall of volleys has a ton of AoE by default and with pathfinders Master Toxicist you spread your poisons and chain stack them too
SSF friendly! I have a few uniques I’ve farmed but none are necessary for the build to function.
Cons
Ranger is not everyone’s cup of tea. I opted to go for a high avoidance using attack evasion + spell dodge and some block. Until you get 20k+ evasion and get close to the spell dodge cap (75%) the build will feel terrible. Without phys mitigation you can absolutely get unlucky and get oneshot by a strong hit or get unlucky and get hit by too many abilities in a row. However if you’re not reckless with your altars and your map mods you can play very safely. You can also pivot defenses to phys taken as+suppression instead but you’ll need some form of recovery.
Not a bosser. You can definitely scale the damage a lot more with more investment but I generally don’t like doing bosses on an avoidance based character even when the damage is respectable. I rolled a Penance Brand Inquisitor for my SSF bossing.
Possible bugs in the skill itself. I saw this video just recently by captain lance showing how Bladefall’s damage is counter intuitive. The skill operates by doing its damage X times where X is the number of volleys. Bladefall of volleys additionally makes each volley in a single cast have larger AoE and more damage. The volley mechanic however leads to weird issues where having more volleys will actually hit the target less times depending on your positioning. There’s more to it as well but at the very least this is very counter-intuitive behaviour https://www.youtube.com/watch?v=ksUW9CTSzV4
Damage calculation is confusing. This doesn’t really matter except for when you’re planning upgrades. Bladefall of volleys with 20% qual hits UP TO 7 times but the PoB assumes you only hit once. There’s no “average hits” like there are with other skills like seismic trap so you have to rely on an assumption of average. I would guess that somewhere between 200%-300% more damage of your base damage is probably accurate (3-4 hits per volley)?
Upgrade suggestions
Obliteration - cheap to farm with Dark Temptation, good enough for damage, but most importantly satisfying chaos damage death pops that make your clear feel even better
Dendrobate - Tier 4 unique is still quite common and this is everything we could ever want - poison damage, duration, es/ev, allres and a free support gem.
Leper’s Alms - Tier 5 unique so it's everywhere. Again everything we could want - poison duration, es/ev/life/block and some suppression. You can probably craft a better rare but in SSF that can take time
Circle of Nostalgia - Finding a good one is the reason I rolled this character. If you can get one with a high roll of chaos damage and buff effect its a huge damage boost
Outside of SSF you can go wild. Mageblood, +2 wands/daggers. Whatever you like. There’s a chance to do a Perfect Agony angle at high investment but I couldn’t seem to get it to work. No matter what I tried just flat poison duration and multi were easier to scale than crit poisons that scaled of crit multi.
