They offer highly conditional pwnage.
For a 75% reflector to be useful you need a couple of the follwoing things to happen:
- You need your opponent to have a decent chance of using the type of icons it reflects
- You need your opponent to have a chance of doing rather a lot of damage of the type it reflects. Note that I said "damage", not "icons" here.
- You need to not have a superior full-blocking or icon based defense option available.
- You need to have a HP-to-opponent's-Str ratio high enough that guessing wrong for a round or two will not automatically lose you the match.
You'll note that points 3 & 4 will very frequently apply to lab pets. Furthermore, point 2 tends to apply to lab pets frequently when they battle in league structures, where they will often be facing opponents with higher Strength but fewer hit points.
Lemme illustrate with a pair of lengthy examples:
Let's assume that HappyChton gets a mildly good lab result tonight and goes up to 936 hit points, and let's further assume that Shattered Rift goes on a Negg binge at the same time gets to exactly 612 HP. Then we fight. My pet has 400 Str boost, Shattered's has 600, so we each would need exactly 72 unblocked unhealed icons to win. Let's assume that I know Shattered is going to cautious attack me with dual WoRs. I have a couple options. First I can try to counter with a similar offense, choosing my dual WoRs and the same stance. Since his pet is stronger I'll take more raw damage than he will (26*13*1.0=338; 26*8.5*1.0=221), but since I have more HP, it will come out proportionately even (338/936 = 221/612) Alternately, I can choose to use my Combo Battle Mirror and my WoR, in which case I'll reflect 7.5 of his 10 light icons back at him, taking only 240.5 damage (18.5*13*1.0) and dealing 208 damage ((13*8.5*1.0) + (7.5*13*1.0)) in return. While he's still dealing more raw damage, that's a relative win for me since 208 / 612 is notably larger than 240.5 / 936.
Now let's assume the inverse case, where Shattered knows that I'm about to use dual WoRs and has to decide whether to use a Combo Battle Mirror or not. We already know that since this is an even match, if both pets use dual WoR, the round is a draw, with the numbers given above. If he uses WoR + CBM, he'll reflect 7.5 of my 10 light icons, thus taking only 157.25 damage (18.5*8.5*1.0) and he will deal 232.75 damage ((13*13*1.0) + (7.5*8.5*1.0)) in return. That looks good at first, but it's actually a proportionate loss, as 232.75/936 is slightly less than 157.25/612. Thus Shattered would be a better off going for the even exchange with the dual WoRs.
Now if species resistances or stance multipliers were different, it might be more advantageous for Shattered to use the reflector, but I wanted to keep the example simple to illustrate the point that raw damage frequently matters more than icons when choosing to use reflectors.
Now to evaluate the 6 available reflectors on my other points:
Flame Reflectozap
This is probably the best 75% reflector in the current weapon mix. Portable Kiln, Ring of the Lost, Ghostkerbomb and Mask of Coltzan all see fairly heavy use and deal significant amounts of fire. Garoo Elite Blaster, Skeletal Fire Gun, Prickly Potion, Glowing Cauldron and Porcelain Hair Sticks also have notable fire components to their attack. So fire is common, and fire in quantity is common. More importantly, the F-Zap is massively cheaper than ANY other viable fire defense option. Wand of Flamebolt and F-Zap 2k are far more expensive, and even though it only blocks 5 fire, Faerie Tabard is still about triple the cost.
Ultra Dual Shovel
Heavily touted as the Pea-killer, this is only worthwhile for the most elite. Since Carrotblade retired, earth is only common in lower end weapons, Essence of Esophagor, Bow of Destiny, Honey Potion, and Ghostkerbomb until you reach the level where FSS and Peas are common. There are many cheaper icon-based shields which can handle EoE, + BoD, Downsize!, Thick Smoke Bomb, Potion of Concealment and faerie abilities can be used to effectively counter once per battle heavy earth attacks. And at the high end, either of the two full earth blockers still in the tower are far cheaper than UDS, while G-Staff is a generally safer bet.
U-Bend of Great Justice
Water is becoming more common than it was before, but there are a grand total of 10 weapons available to neopians that can deal 6 or more water icons, one of which is Glittery Faerie Dust, And even in the case of mass water attacks, EKST is a lot cheaper or Faerie Tabard is a lot better.
Combo Battle Mirror
Granted, my lab pets has stats very favorable for reflection, but I don't know why this doesn't get more respect. There are few heavy-light weapons (Skarls, SAP, FSS, Kaylas AoT), but there are a plethora of common 3-5 light weapons (RotL, Bzzt, Pike Pike, Scuzzys, SoRF, GoC, WoR, PCC), and they are fequently used in combinations due to the usefulness of light in overruning shields. Since there are notable drawbacks to both full light blockers in the HT (PCH and J-Ring), the only real alternative for mass light defense is the cheaper-but-not-for-long Shadow Shield.
Triple Turbo Dryer
This is solid, with the commonality of WoR, Bzzt, BoD, UBG, PCC and GSword in pro-level battling. There aren't many air defense options (RoW, S-Soar), but the current price on this just scares me, as I am irrationally afraid that TNT will eventually hire someone who knows what they are doing in the BD and release better air defense options.
Ultimate Dark Reflectorb
At the moment dark is not all that common, but there is a hyper-common mass dark weapon (SoS) and 2-3 more somewhat less common mass dark weapons (DFC, J-Ring, J-Pot) as well as one elite (WotDF). That would make dark reflection attractive, except that this is not priced competitively against the generally superior options of GShield or RoTL. Even MoC and Kaylas can fare decently against some of the heavy dark weapons. If you can find a UDR for the 2.5-3.5mil that CBM and F-Zap trade for, then it's worthwhile. At the 4-8mil people ask, this is just nuts.
