How much prebuffing do you need for your build to be viable. At some point, people just wanna join games and farm right away. Dont mistake me, your points are all good, but not every1 wanna carry a stash full of prebuff stuff
well there's a question of how much you need to do and how much you're willing to do
some things are just +1 skill for an extra few clicks, some are +5-6 for one click, and some items could be kept equipped because they are already pretty near BIS
for example I just keep arachs, sojs, magefist & enigma equipped, same with swap cta/spirit, and swap out the other items.
Its one shift click each to swap;
>mang songs <-> insight
>+3 circlet <-> your choice of helm (could be +3/20 and keep it on full time)
>+3 ammy <-> your choice of ammy
>+4-6 tome <-> ars baalos (can use 2 extra tomes, one for bind demon if wanted, and extra click)
>wraithsteps <-> resist boots
Now where you start getting into the excessive stuff is when you need to start moving charms around for room, opening inventory, swapping rings (can only shift click your left ring slot), using a skill shrine, etc
Its pretty fast depending on your setup to ctrl+click your cube/tome out of inventory and put charms in, then undo that after summoning tainted at the start of the next game
Its also an extra few seconds if you want to use a waypoint to cast BC before summoning tainted, whereas you could simply cast it without BC and have -1 skill and save that time
Those are all sort of tradeoffs for time. There's stuff I won't bother with, like hunting down a skill shrine, and it takes me about 10 extra seconds at the start of a game and end of a game, since I have my inventory arranged to just shift click everything in a row
I have a bone break so will test this next game
don't think I notice any difference, but my tests could use a bit of work tbh. Maybe it needs to be equipped at the time of binding?
I'm not even sure physical sunder would have this effect on minions at all, ie testing on a grizzly bear with amp from druid.
