As has been suggested, and agreed to by many, I think that weapons should be added to the shadow lair gear, this would give more reason for people to do shadow lairs, which are fun, it would also just be cool. The weapons would be upgraded from 4*s, like the SL armour pieces.
Here are the icons for the suggested weapons: http://imgur.com/gl2DcAp
For the rabid snarbolax twins:
The weapons could be poison variants of the Barbarous thorn blade and the Dark briar barrage, they would do slightly less damage but have a chance of poison, fairly straight forward. perhaps the sword could be called the Bubonic thorn blade?
There could be a snarbolax gun called "The Thorn" which is of the magnus line, Here is an image for the icon: http://imgur.com/T7E3q5W
The thorn does considerably less damage than the Callahan and the Iron slug, but in turn it has a high chance of dealing weak poison to enemies, and has a very high damage boost against poisoned enemies. As a result, the thorn would initially be weaker than the other magnus lines, but if shots could be chained in succession it could do more damage. The Thorn would shoot a snarbolax spike, like the snarbolax does, the charge would be like the other magnus charges in that it shoots a powerful bullet that pierces enemies, except it poisons enemies instead of stuns.
For the Ice queen: (second row for icons)
The weapons could be the blast jelly bomb, and the ice jelly bomb, these would be upgraded from the Radiant sun shards. The jelly bombs would be similar to the shard bombs in that they have an initial small bomb which explode and make smaller cluster bombs, but the jelly bombs would drop more bombs which are smaller and spread out randomly, like a super blast jelly. The mini jelly bombs would explode at different times, some being earlier and some longer, One of the main differences from the shards bombs would be that the cluster bombs are created at the centre of the bomb and move outwards until they hit a wall or enemy. Statwise they'd be pretty similar to the scintillating sunshards, in that they deal piercing damage, however the ice jelly bomb as you would've guessed has a small chance of causing minor freeze, in exchange for some of its damage. The jelly bombs are capable of doing more damage than a shard bomb if placed well due to having more explosives, but is more unreliable as its semi random so some enemies will be damaged more, while others are damaged less.
For the red roarmulous twins: (third row for icons)
The weapons could be reskinned versions of the mixmaster/celstial oribtal gun, they would be upgraded from pulsars of the corresponding element. Perhaps ones for the other two pulsars could be made aswell. I'm not sure what to name them, so if anyone has suggestions I'll put them up here.
For Shadow-fire Vanaduke: (fourth row for icons)
The first weapon could be a 5* winmillion, perhaps it could visually have the divine theme to fit the almiran crusader theme or just simply a shadow theme. The second idea would be a shadow-fire fang of vog, it would be quite similar to the original fang of vog in that it can set things on fire and is like a leviathan blade, except it does shadow damage and its charge would have an additional chance to curse, the charge would deal slightly less damage than the fang of vog's. for this to be viable both it and the fang of vog would need to be buffed in that the chance of self-inflicted fire should be removed (perhaps replaced with reduced movement speed for a few seconds?). A possible name could be shadow of vog, I'm not so sure about names so if you have one please do suggest it.
So comment to say what you think of these ideas, if you have any others, do share.
I love my Dark Briar Barrage solely for its strong damage. I don't know how well Poison may help; it should have a good chance of inflicting Moderate Poison or higher. Otherwise I would be put off by its lowered damage.
Furthermore, we already have a Poison Pierce Autogun: The Plague Needle (Coliseum Recipe)
The mini jelly bombs would explode at different times, some being earlier and some longer.
If one little bomb causes Freeze, the others would most likely break it. It would not compensate for the lower damage output and its theme to the Ice Queen.
I still like the idea of a Blast Cube Bomb.
Those who paid so much money for an exclusive item that suddenly becomes available to all will stir up anger for they basically spent more than those who 'waited out' for the Mixmasters/Orbitguns.
We will virtually destroy all potential in most other Handguns. If you have not seen how Mixmasters/Orbitguns operate, you should know each little 'frisbee' deals the equivalent damage of a Nova Driver. Given each shot launches two frisbees and it is a three-clip Handgun, it's DPS would easily dwarf Alchemers, Arcana, and Polaris. I'm sorry for being blunt, but this would basically ruin Gunslinging (No one in Lockdown would want me spamming these demons. Well, no one in Lockdown would be safe from each other.)
Perhaps instead we could play with Catalyzers... I have an idea...
The Shadow of Vog is greatly overpowered, having the ability to deal two Statuses, with one being CURSE. Perhaps have it just deal Shadow Damage like the Phantom's blade, with a low chance to deal Minor Curse on its charge only. Even then, it would probably act like a status Acheron with different charge. I vote no for this.
So, my opinions on your current ideas. I have my own ideas, but then I'll be spamming my own agenda. They're in another thread separate.
You have some good ideas, Dagunner!
