Building without even a grappling hook can be a pain XD but if such happen I would usually just cheat in a cosmic car key via cheat sheets, finish the roof or whatever and then throw away the cosmic car keys.
Gizmo pack can be a huge help with building, but I honestly never tried building potion before XD also, neither calm potion. if you build in or near the/a town, it will disable monster spawning anyway, and if you build elsewhere... well... yeah, that can be annoying XD but even reduced enemy spawn would be annoying too those times XD
But then, you can just use godmode while building, so you won't end up massacred by a giant turtle while finishing a roof... XD
I assumed something like that. but RNG can hate collectors XD so, yeah, a town NPC selling boss summon item sounds good, but, then why post golem? would it be too cheat-y, to have them appear in his shop once the respetive boss is down once in the world? sure, you could abuse it for loot to sell, but still, at that point, it would sound more useful (and it's not like you have to buy them if you don't want)
also, why a cultist?
You mean something like automatically putting stuff in chests? but it would only work organised, if said chest is already "full", that is, has at least one of the item and each slot taken by an item, right? also, yes, favorite items, otherwise... uhh, that's no fun XD
I kinda get what you mean, but still. Also, why would you want to get lots of them once? again, it might be just me, but I would usually just buy an ironskin and an endurance potion or something before a boss fight. no point buying more than one, when you can buy more any time you want. well... mid-fight that might be difficult, but that aside XD And some more potions once available. perticularly lifeforce!
As for architect, wood is also a questionable thing, I don't know if he sells wood or not, but that's very useful too (there's a mod like lumberjack NPC - wood is renewable, can be cultivated, but it takes time...)
Preparing before events, money-wise? like how? Or you mean, regarding items? it's usually useless trash I have in chests. it probably worths some money, but still. I did just recently realised though how profitable it is to farm BoC. crimtane bars sell really well. (I guess that returns us to "being able to buy summon item early game can be abused, but still.)
Many of the cell phone's functions have little use (IMO)... like how far you're from the center of the map... depth meter have use in like when you try to loot the dungeon pre-skeletron, but otherwise usually negligable. and several other functions too. can be useful in cases, but for example, DPS... it's interesting info, but when you actually busy dealing lots of dmg (like in boss fights or events) you probably won't look at it, because you're busy XD
so, yeah, the cell phone is overrated, I guess, but it takes up only a single slot so that's cool.
