I would offer my ten rings. The higher level should replace the lower level. With the exception of level 1, 4, 7, 9, 10 which can be switched back and from. These weapon corresponding to Derringer (ring 1), Machine pistol (ring 4), Shotgun and cannons (ring 7), Rocket launcher (ring 9), Beam/energy weapon (ring 10).
1) Single-barrel Derringer : single-shot handgun, can only hold one bullet at a time. Gain a barrel at lv 13, 16 and 19 (max 4 barrels at lv 19, and therefore can shoot 4 bullets at the same time if you choose to do so, or you can shoot a few and save one or two while confirming the status of the target). At lv 20, gain a second Derringer. In short, you can dual-wield Derringers at lv 20.
2) Revolver : single-shot handgun, its cylinder has multiple chambers can hold up to three bullets. The higher the level the more chambers and therefore, more bullets can be held. Start with 3 at level 21. Each two levels give one extra chamber, max 7 at level 29. Note: since one of your two derringer evolved into revolver. When dual-wield, you can only carry one revolver and one derringer.
3) Semi-auto Pistol : single-shot handgun with a magazine replaces your revolver. Greatly increase reloading speed and ease reloading difficulty. Magazines start with 7 bullets at lv 31. Each lv up gives 1 extra bullet capacity. Max 16 bullets per mag at lv 40. Same dual-wield rule applies: one semi-auto and one derringer.
4) Burst-mode Pistol : You can switch between semi-auto and burst-mode. In burst mode, can shoot up to 4 bullets in a quick burst. The number of shots per burst can be selected. Lv 42 to lv 46 increase mag size by 2 per lv (max 26 at lv 46). Lv 47-50 increase the max number of shots per burst by 1 each lv (max 8 shots per burst at lv 50). Note: burst mode pistol shoots continuously a selected number of bullets per burst from its single barrel. While the derringer you wield in dual-wield unleashes four shots immediately thanks to its 4 barrels.
5) Semi-auto rifle : You gain the 3rd weapon (your other weapons are the Derringer from ring 1, and the semi-auto from ring 4). Unlike handgun, rifle's attack is far more accurate, better range and greater power. Start with 15-bullet mag. Mag size increases by 5 at lv 52, 54, 56, 58 and 60 (max 40 bullets per mag at lv 60). Power, range as well as qi or mana consumption per bullet +30% per lv at 51, 53, 55, 57, and 59 (max +150% at lv 59). Note: Your bullet power did scale with your lv. The +30% is just a multiplier on top of the normal scaling.
6) Sniper rifle : Sniper rifle replaces semi-auto rifle. Sniper rifle gives ability to see and aim far away as well as being more accurate than Semi-auto. Zoom function start with x5 at lv 60, becomes x10 at 62, x20 at 64, x40 at 66, x80 at 68, x160 at 70. Lv 61, 63, 65, 67, 69 increase power, range and accuracy (+20% per lv). Power scaling applies similarly.
7) Shotgun : Shotgun replaces Sniper rifle, however, you still retain the scope. Shotgun shoots shells similar to cannon instead bullets like rifle. More shell types are unlocked as you lv up. You gain only 2 types at lv 70 (slug and scatter shot).
Lv 71 gives Armour piercing (AP) round which cost more qi or mana to make but has greater penetration on hard surface. Lv 72 gives Exploding round which explodes upon impact. Similar to AP round, Ex round takes more qi or mana to make than slug and scatter. Lv 74 gives corrosive (Cor) round. Lv 76 upgrades scatter shot into Piranha (Pi) round, replacing the round shots with sharp tacks.
Lv 73 and 77 increase barrel diameter by 100% (hence the shells you use also increase in size and power but retain the qi or mana consumption cost of smaller size). Max barrel size is 300% (or +200%) at Lv 77.
Lv 75 allows you to switch your shotgun with a single-barrel naval cannon turret (40cm in diameter). Size, power, range, and consumption of the weapon drastically increases. The cannon can use all the unlocked shells.
Lv 78 makes the turret from single-barrel into triple-barrel turret.
Lv 79 the turret becomes a flying addon that follow you everywhere and shoot at enemy according to your will. You can now use the shotgun together with the cannon turret.
Lv 80 You gain another triple-barrel turret.
8) Fully Automatic : Your pistol become Machine Pistol where it can shoot continuously by pulling the trigger and holding it (90 shots per min). Lv 81 to 83 increases the mag size to 50, 100 and 200. Lv 84 makes your shotgun fully automatic using an ammunition box with a rate of 80 per min. Lv 85 to 88 increase firing rate to 200, 800, 2000, 5000 per min and ammo box to 100, 250, 500 and 1000. Lv 89 gives you two quad-barrel auto-cannon turrets (3.5 cm in caliber). Lv 90 gives four more additional quad-barrel auto-cannon turrets while increases firing rate of your triple-barrel cannon turrets from 1 per min per barrel to 20 per min per barrel.
9) Rocket launcher : the idea is to shoot out self-propelled guided warheads. Lv up increase the number of barrels (2 at 95, 4 at 99) and the types of warhead (explosive at 90, Hardened solid warhead at 92, toxic gas at 93, corrosive at 96, high explosive armour piercing at 97, nuke at 98)
10) Beam weapon : firing a continuous stream of energy at the target. Also improve the power of Derringer to shoot black hole bullets instead of normal bullet (blackhole bullet turn into blackhole upon impact, the blackhole last for 10s). Enhance Autocannon and shotgun to make them shoot anti-matter shells. Machine pistol will now shoot Qi/mana devouring bullets which easily rip apart mana/qi constructs.
For ability, you can put shields and disrupting devices there.
