Greetings, no doubt your joy of the game and the thirst for knowledge has brought you here, a small piece for new players on how to help fly your dragons. It's a complex game indeed once you start digging deep, so I've put together a simple bit of information.
I'll begin the first R with reconnaissance. Basically know your enemies layout, either having a run through the map beforehand so you know where the mages are, or if they cluster huge groups of the same towers together so you can add a passive resist spell to help your health and also farms and mills locations. It's always nice to know where they are too I find, all clustered at the end?Then you only have to destroy the first lot of towers on home island or if they are scattered, you will have towers mid way gaining a health regeneration and a tougher fight at the end. This recon info can even be gained by having a team mate call out during flights in battlechat, always good to know whether you can prepare a spell in readiness before you finish the turn on a run or will a Mage cancel it out. These can be as simple as just calling the colour of the Mage towers coming up, or location placed on islands too. Very useful habit to get into.
Second R, Range
I still watch replays and see people trying to burn down towers that are too far away whilst the nearer towers are draining their dragons health. Everyone has towers they like to hit first, mine for instance may be different to yours, the variety of towers, base sizes and dragons lead to different objectives every flight you take. Sometimes there isn't no range at all, take Shrine and Temple islands, both straight of a turn and both consisting of 5 plots to place a tower, these will all attack at once, what I'm talking about is the long runs, Long Island and Home base especially. The range of a dragons fire is limited so it's first come, first served in wholesale destruction once your primary towers have been destroyed within range. So don't try to knock out the storm tower which hasn't woke up yet as you're too far away and concentrate on them trying to ruin your day by shooting at you.
Rage is the lifeblood of an attack, unless attacking a base far lower then your level, a dragon with out rage is just a huge flying meat filled target. So apart from a minimum of dragons who have "free" spells, i.e. Phasmos ice shock and the passive resists added to dragons or that can be equipped to dragons, rage fuels the rest of the spells. Shields, fireballs and the whole rest of the list require rage to be used in their application. So you have to know when to use rage, when to save it, best time to store it, how not to waste it and how much will the next team mate backing you up need? The cost of rage varies too from the different type of dragons and the ranges of spells and not forgetting the double cast spell too I.e. Crumble to dust. Also, good news. There are ways to help with rage in battles and these are found in the various size (commons to mythic) runes and glyphs which can be added to dragons to speed up the regeneration of rage and in the research hut which you can increase the amount of rage you begin your battle with.
Obviously this is just a brief summary, but should give the new players an insight on how to gain the best of an attack run rather than just going in blind. Hope it helps.
PS All this way and I never mentioned cider once, I reckon I deserve one for that
