[Argmaster]

This is a proposal to add white opal gem stone to the game.

Physical properties:

• hardness in Mohs scale: ~6
• density (at 20° C): 2 g/cm3

In game properties:

• behavior similar to gemstones - provide special effect instead of stats

Modifiers

• luck - chance to do double damage to block/entity, to not lose durability or possibly double drop chance for rare things (apples?) or generally to double drops. Tool Material Modifier Ideas #172

Spawn rules

• -3000 < Z < -300
• Never spawns in veins

Related to: #1269

generally to double drops

that would be too OP

I think chance to do double damage is good enough, though I feel like white opal doesn't fit that. Could call it something like Critstone, and also make it lower the durability of the tool/weapon slightly.

There is no reason to stack additional penalties on this material because opportunity cost of replacing high durability metal with low durability gem is already doing that. It should be an emerging behavior. Secondly it is beneficial for it to have different uses for different tools so it is actually useful and you have purpose for more than 5 throughout your whole gameplay. And the last thing, if we follow this naming though process instead of ruby providing life steal we should make vampirestone, instead of topaz doing electrocute we should have electrostone etc. This is not design choice we are going for I believe.

Imo this purely depends on how often that happens. If it happens every 10 blocks, wow, you get additional 40 drops per iron pickaxe, really balance breaking.

Imo we should have many modifiers that have small impact on their own, so they can be mixed and stacked in a fancy and fun ways. Right now modifiers are way to impactful, single item can define how powerful or how weak a tool is.

Also, once again I am reminding you about opportunity cost of replacing iron with a gem. I don't think that fragile modifier is necessary on gems with low durability on their own and I also think that iron pickaxe with a diamond tip should be generally better than just iron pickaxe. Rigth now it is not, it is faster but breaks quicker so overall there is little benefit in investing that gem into pickaxe.

I didn't say we should rename all the gems, just this one. Also, I'm a firm believer that ores and gems shouldn't be the answer for everything. We have to consider exploration, mob loot, structure loot, etc.

Things may sound good on paper, but then in practice, suck.

Well, the problem is that you can just stick your valuable ores back into the rock it came from. That's what makes it OP.

Diamond pickaxe takes less swings, so it halving durability seems totally reasonable, given that durability is per swing. If you take this into account, then I'm pretty sure that you can break the same or more blocks than pure iron pick, and it's faster too.

I would just call it Opal. White opal is the prototypical opal.

I feel like white opal doesn't fit that

"In the Middle Ages, opal was considered a stone that could provide great luck because it was believed to possess all the virtues of each gemstone whose color was represented in the color spectrum of the opal" this is where I got the idea, I liked the idea of opal having rainbow powers

Alternatively, the lucky modifier could increase mob drops (which shouldn't be a problem if they don't respawn?), or for accessories, give a chance to dodge some incoming damage?
