This is a brief guide to hybridization, it will give some basic help to people trying to break the bonds of a single weapon type while still being good at what they like.
Getting specialized armor first makes it easier to start supplimenting other armor types to hybridize.
The first step for hybridization is learning what you like to play as and compromizing between the two. if you want all 3 weapon types, grab a chaos set, heat your weapons to level 10 and grab a swiftstrike buckler and you'll have ASI H, CTR VH and DMG M blanketed and can use trinkets to help fight off death by status effects because you will be weak to them. or otherwise specialize a bit and can stop reading now.
Once you have picked your weapon types, it is time to start focusing on fleshing out your armor and trinkets.
Armor
Due to armor and trinket slots, you can only get 2 max bonuses (assuming CTR is one of them) for your weapons abilities of CTR, DMG or ASI without uvs, assuming your weapons are heated to level 10 (mask of seerus allows two maxs and an ASI low). Bombs are great for hybridization because they don't need ASI and that simplifies things.
Since you can have only two maxs start planning your focus, ASI, DMG, CTR and on which weapon types, Swords, Guns or Bombs. This traslates to 8 possible choices to focus on.
All weapons at level 10 have CTR medium, so heat up your weapons, and you'll have CTR med across the board without specializing armor yet. It is best to, from there to choose damage type resistances and pick armor to work towards that give bonuses to the weapons you choose. Try to get at least one piece that resists a combination of shadow, elemental or normal. from there pick your trinkets from the focus modules that give bonuses to those weapons. It is best to get blanket DMG armor because uvs can suppliment CTR or ASI more efficiently.
for example a CTR VH UV on a level 10 weapon yeilds a CTR max without armor bonuses while it takes 2 uvs to get efficient damage bonuses of VH against the two families weak to the weapon type (unless normal weapons were used) though some have built in damage bonuses, those are specifics and this is more of a general guide.
Sheilds
Sheilds there are few sheilds that help players expand their abilities and they are the Swiftstrike Buckler and the Barbarous Thorn Shield lines.
They help give bonuses that free up armor for the game of compromising between gear.
Trinkets
Trinkets are pretty self explanitory with focus modules.
Tired, going to bed, will add more another time.
while i see why it is posted under the arsenal, maybe a shadow copy?
A couple of points to add to your post as well:
SSB (swiftstrike) gives ASI high, not medium.
I would mention that Chaos set gives the CTR and DMG med (like you said) but comes with a host of debuffs as well.
I would also mention that if you are planning on going hybrid, prepare to make more than one equipment set. Divine Veil and Skolver coat cover all your bases, yes, but it is best to have full defenses if possible, especially if heading into fiend levels. Same with shields.
When it comes to weapons, if you are going hybrid, it is generally as a split swordsman/gunner, and at that point prepare to have 3 weapon slots opened. Two swords and one gun, or in my case, one sword and two guns. Playstyles will vary, but giving yourself the option of attacking at a distance to whittle down health, then closing with the sword to finish the weakened foe off is a fun way to do it, and safer.
Overall, it comes down to choice; I have rarely seen a bomber hybrid (aside from a bomber with a backup sword), it is usually a swordie with a sidearm. The difference between that and a hybrid is the ability to use both effectively, as opposed to one as a backup. Im rambling now, and I think the medication is kicking in, so hopefully Lycheesoup will come help make sense of this soon.
