Attack Ring: Dragon Breaker
Weight: 7.5g total
The Core AR is the heaviest of all Core ARs. When used with Screw Zeus (the heaviest Sub AR), the combined weight is enough to slow down slower Attack tips, which can be detrimental.
Core AR: Dragon Breaker
Heaviest Sub-Ring Compatible AR in the game.
Very aggressive design in both left and right spin.
Not useful with its own SAR due to the deficiencies of the latter.
With War Lion SAR:
War Lion's SAR doesn't protrude past Dragon Breaker's contact points, and is merely used to fill the Sub AR spot.
Suffers from heavy recoil, but once controlled is surprisingly powerful, albeit not enough to be competitive in its own right.
Nonetheless comfortably Tier 2 for Smash Attack.
With Screw Zeus:
This is the heaviest AR setup possible - usually not an ideal thing for Attack but on fast tips this gives it a significant edge against Weight Based Defense compared to other ARs, and makes it somewhat harder to push around.
While not as much as in left, Dragon Breaker nonetheless brings some additional smash to the setup even in right spin, and still exposes the important contact points of Screw Zeus
Works about as well on SG Metal Flat Base (Gaia Dragoon V Version) as conventional Smash AR's, perhaps a little more power at the cost of a little more recoil.
Arguably a safer choice than left spin setups on taller bases, due to the lack of inverted slopes that could cause the combo to "upper" itself, though this is marginal.
Overall one of the best attack AR setups as long as you have the right parts, and one of the best choices for Defense Grip Base (Tip Inverted), due to the weight and Weight Disk-overhanging contact points.
Primary contact points are the rear of the heads of Screw Zeus, the corner of the sloped section, and the ridges of Dragon Breaker, and against lower opponents the overhanging protrusions also make contact. All of the parts of Screw Zeus pack powerful Smash Attack.
Overhanging contact points of Screw Zeus allow better performance against low opponents but can cause some issues against Circle Survivor Defense, largely relying on a strong launch and weight to bludgeon such combinations out of the arena.
Weight allows it to be a little "safer" than alternatives such as Square Edge due to being harder to push back or counter.
With War Lion SAR:
Again, War Lion is only used for legality and the fact it keeps out of the way.
Fairly severe recoil, once controlled enough to work (this being the limit of what is possible), produces very powerful Smash Attack, due to well exposed contact points, however it is just short of making the competitive combinations list as War Bear is directly superior.
Nonetheless, a usable, viable setup.
With War Bear SAR:
Combined with the right weight disk (any Wide Weight Disk will usually work) and a relatively fresh War Bear SAR, fixes the SAR in place, allowing its excellent range and aggressive, well angled contact points in this directions to be used for attack, while Dragon Breaker provides additional Smash Attack to boot.
Suffers from fairly high rotational recoil, but surprisingly moderate regular recoil, allowing it to work on SG Metal Flat Base (Gaia Dragoon V Version), though like Mountain Hammer, controlling the rotational recoil results in a dramatic improvement in power.
War Bear SAR's ridges wear down over time (the mold with raised circles as seen in Hasbro's Hyperblade version wears down much faster and is looser to start with), allowing it to shift on contact, reducing its power dramatically. While some shifting on hard hits is normal, after a certain point, replacement is required - and this is in addition to moderate breakage issues. Luckily, Galzzly is relatively cheap and easy to find.
It is worth noting that Great Dragon can provide arguably more powerful performance with higher speeds and more exposed primary contact points and focussed weight, though that setup only works on rubber tips.
With Screw Zeus:
Dragon Breaker is an effective AR in its own right in this direction, and adds additional power to Screw Zeus.
One of the most powerful AR setups in the game, though the fact this is also the heaviest AR setup of the generation means that it requires a very fast tip with good traction, such as SG Grip Change Base Tip or Defense Grip Base (Tip Inverted) to really hit hard.
However, Great Dragon also adds to Screw Zeus without being as heavy, which means it does carry some advantages on more worn tips.
The additional weight however means on a fast combo, Dragon Breaker will do better against heavy, low-recoil opponents, and thus is perhaps a slightly better choice here. It also makes the combo much harder to knock out than some other options.
Also a better choice on SG Metal Flat Base (Gaia Dragoon V Version), probably thanks to the extra weight. However, not really significantly better than conventional Smash ARs here.
War Bear SAR works better with Dragon Breaker on slower bases due to the lighter weight being easier to move fast. It does however have more wear and breakage issues, and overall is less effective (and should be considered for use with Great Dragon instead of Dragon Breaker)
Primary contact points are the forehead of Screw Zeus, the rear spike protrusion and the mass behind it, as well as the serrations of Dragon Breaker. All of these provide very effective Smash Attack, with Dragon Breaker mostly taking up dead space on Screw Zeus (as the spikes it covers are not great contact points). It is worth noting however that it does even out the weight distribution quite noticeably, rather than focusing it.
Compared to Right Spin, the inverted slope on Screw Zeus results in destabilisation of the Beyblade using it when hit. As such, taller bases can struggle slightly more against low opponents though generally this is negligible. The overhanging section can also still interfere with efficacy against Circle Survivor Defense however, and a very strong launch is needed to basically use weight and momentum to bludgeon these combinations out of the arena.
Sub AR: Dragon Breaker Sub AR
Aggressive Sub Attack Ring that cannot be fixed in place by any extant AR.
Angles are quite recoil laden.
Size creates leverage for opponents, giving it some vertical recoil issues.
Tends to obstruct contact points of offensive ARs.
Even if it could be fixed in place, the angles would make it too recoil prone.
It is quite competent on Great Dragon, with decent synergy in Left Spin making it able to land some solid hits. If a small SAR is unavailable, Dragon Breaker Sub AR is a fair option.
It is not entirely bad specifically on Gyro Engine Gear combinations due to its large size and the exposure these give the underside of SARs. While still too recoil prone to be a top-tier choice, it is quite acceptable in a pinch.
